SOUTHERN DISTRICT OF MISSISSIPPI
NORTHERN DIVISION
ELVIN SHEPHERD PETITIONER
V. CIVIL ACTION NO. 3:25-CV-421-DPJ-ASH
WARDEN, FCC YAZOO CITY RESPONDENT
REPORT AND RECOMMENDATION
Petitioner Elvin Shepherd, Jr., a federal inmate, filed this petition under 28 U.S.C. § 2241
challenging the Bureau of Prisons’ calculation of his sentence. As explained below, the
undersigned recommends the Court deny Shepherd’s petition.
I. Facts and Procedural History
On January 25, 2018, the federal grand jury in the Western District of Louisiana handed
down an indictment charging Shepherd and others with federal drug-trafficking charges. On
February 21, 2018, Louisiana state authorities arrested Shepherd on separate state drug-
trafficking charges. Shepherd remained in state custody until March 6, 2018, when he was
temporarily transferred to federal custody pursuant to a writ of habeas corpus ad prosequendum.
While he was in federal custody, Shepherd picked up a new state charge on July 6, 2018 (“State
Charge #2”), his original state charges were dismissed on August 1, 2018, and he received a third
state charge on July 6, 2019 (“State Charge #3”). In the meantime, on June 25, 2018, Shepherd
pleaded guilty to one federal charge, and on July 18, 2019, the federal court sentenced Shepherd
to serve a 120-month term of incarceration with the BOP. The federal sentencing court’s
judgment recommended that Shepherd “receive credit for time served while in federal custody
since February 21, 2018.” McEvoy Decl. [6-1] Attach. 5 at 2. On July 19, 2019, Shepherd was
returned to the custody of state authorities for resolution of open state charges.
On August 22, 2019, the state court sentenced Shepherd on State Charge #2 (the July 6,
2018 charge). For that charge, Shepherd was given a one-year sentence of hard labor, with credit
for time served since February 21, 2018, to run concurrent with any other sentences. That one-
year, time-served sentence was fulfilled on February 21, 2019, but Shepherd remained in state
custody. On March 25, 2021, the state court sentenced Shepherd on State Charge #3 (the July 6,
2019 charge). For that charge, Shepherd was sentenced to one year of hard labor, with credit for
time served since September 12, 2019, consecutive with any other sentences. That one-year,
time-served sentence was fulfilled on September 11, 2020. Shepherd remained in state custody
until March 31, 2021, when he was turned over to the exclusive custody of the United States
Marshals Service.
The BOP has calculated Shepherd’s federal sentence as beginning on March 31, 2021,
and has awarded him 403 days of jail credit for the periods from (1) February 22, 2019, through
September 11, 2019 (202 days), and (2) September 11, 2020, through March 30, 2021 (201
days). In other words, Shepherd has been given credit for the time between his sentences for
State Charge #1 and State Charge #2, and for the time after his sentence for State Charge #2 ran
but before he was transferred to BOP custody. Believing he should receive additional credit
towards his federal sentence for time he was in custody between February 21, 2018, and March
30, 2021, Shepherd filed this habeas petition on June 10, 2025. See Pet. [1] at 5 (asking the Court
to “direct[] the BOP to credit Petitioner with an additional 730 days of prior custody credit”).
Respondent answered [6] the petition, and Shepherd filed a reply [8].
II. Analysis
“The BOP is responsible for calculating sentencing credit, and the proper vehicle for
raising . . . a challenge [to that calculation] is a petition pursuant to 28 U.S.C. § 2241.” United
States v. Sonsteng, No. 2:17-539, 2021 WL 2380054, at *1 (S.D. Tex. June 9, 2021) (citing Pack
v. Yusuff, 218 F.3d 448, 451 (5th Cir. 2000)). Before filing a § 2241 petition, “[a] federal
prisoner seeking credit on his sentence . . . ‘must first exhaust his administrative remedies
through the’” BOP. Castano v. Everhart, 235 F. App’x 206, 207 (5th Cir. 2007) (quoting United
States v. Gabor, 905 F.2d 76, 78 n.2 (5th Cir. 1990)). Respondent does not suggest Shepherd
failed to exhaust, so the Court turns to the merits.
“After a district court sentences a federal offender, the Attorney General, through the
BOP, has the responsibility for administering the sentence,” including “determining the amount
of a defendant’s jail-time credit.” United States v. Wilson, 503 U.S. 329, 335 (1992). Whether the
BOP has properly calculated a prisoner’s sentence “raises two issues: (1) when his federal
sentence commenced, and (2) whether he is entitled to credit for any time in custody before the
date his sentence commenced.” Curry v. Wingfield, No. 3:24-CV-141-DPJ-ASH, 2025 WL
2076472, at *5 (S.D. Miss. July 11, 2025), report and recommendation adopted, 2025 WL
2076473 (S.D. Miss. July 23, 2025).
A sentence’s commencement date is set by statute: “A sentence to a term of
imprisonment commences on the date the defendant is received in custody awaiting
transportation to, or arrives voluntarily to commence service of sentence at, the official detention
facility at which the sentence is to be served.” 18 U.S.C. § 3585(a). BOP Program Statement
5880.28 explains that under the statute,
[i]f the prisoner is serving no other federal sentence at the time the
sentence is imposed, and is in exclusive federal custody (not under
the jurisdiction of a federal writ of habeas corpus ad prosequendum)
at the time of sentencing on the basis of the conviction for which the
sentence is imposed, the sentence commences on the date of
imposition, even if a state sentence is running along concurrently.
BOP Program Statement 5880.28, at Part 3.b. In this case, Shepherd was not in exclusive federal
custody at the time his federal sentence was imposed but instead in federal custody pursuant to a
writ of habeas corpus ad prosequendum. See Washington v. Chandler, 533 F. App’x 460, 461
(5th Cir. 2013) (“When [the petitioner] was transferred to the Northern District of Texas
pursuant to writs of habeas corpus ad prosequendum, each transfer was ‘only a “loan” of the
prisoner’ such that Texas retained primary jurisdiction.” (quoting Causey v. Civiletti, 621 F.2d
691, 693 (5th Cir. 1980))). So the commencement date was the date he was finally turned over to
exclusive federal custody to begin service of his federal sentence—March 31, 2021.
The next question is whether Shepherd is missing any credits for prior custody to which
he is entitled. Title 18 U.S.C. § 3585(b) explains that a prisoner
shall be given credit toward the service of a term of imprisonment
for any time he has spent in official detention prior to the date the
sentence commences—
(1) as a result of the offense for which the sentence was imposed;
or
(2) as a result of any other charge for which the defendant was
arrested after the commission of the offense for which the
sentence was imposed;
that has not been credited against another sentence.
Applying this statute, the BOP awarded Harris credit for 403 days in custody: from February 22,
2019, through September 11, 2019 (202 days) and September 11, 2020, through March 30, 2021
(201 days). McEvoy Decl. [6-1] ¶ 25. The remaining days between February 21, 2018, and
March 30, 2021, were credited towards Shepherd’s state sentences. Id. ¶¶ 18, 19.1 Shepherd
1 Shepherd served 365 days for State Charge #2 (from September 21, 2018, to September 21,
2019), and 365 days for State Charge #3 (from September 12, 2019, to September 11, 2020). The
total amount of time from his arrest on February 21, 2018, through his last day in state custody
on March 30, 2021, is 1,133 days. This is the sum of his two years in state custody (365 + 365 =
730) and the 403 days he was credited by the BOP.
has not shown that any of the time he was in custody before his federal sentence commenced
(and for which his federal sentence has not been credited) has not already “been credited against
another sentence.” 18 U.S.C. § 3585(b). Instead, it is clear that all such time was credited toward
his state sentences. The BOP has correctly calculated Shepherd’s sentence.
What of the federal sentencing court’s recommendation that Shepherd receive credit for
“time served while in federal custody since February 21, 2018”? Reply Ex. A [8-1]. It is well-
settled that “the calculation of credit under § 3585(b) rests with the Attorney General (through
the BOP), not with the court that imposed the sentence. Consequently, ‘[b]ecause the
[sentencing] court lacks the authority to award or deny credit, the BOP is not bound by its
decision.’” Smith v. McConnell, 950 F.3d 285, 288 (5th Cir. 2020) (quoting In re U.S. Bureau of
Prisons, Dep’t of Justice, 918 F.3d 431, 439 (5th Cir. 2019)) (additional citation omitted).
What of the fact that the state court, when it sentenced him for State Charge #2 on August
22, 2019, ordered Shepherd’s one-year state sentence to run “concurrent with any other sentence
serving”? McEvoy Decl. [6-1] Attach. 6 at 2. Shepherd was not then serving his federal sentence;
it did not commence until March 31, 2021. That state-court sentence could not run concurrently
with a sentence that had not yet begun.
Shepherd also complains that the BOP declined to grant him a nunc pro tunc designation.
See Pierce v. Holder, 614 F.3d 158, 160 (5th Cir. 2010) (“Where a federal sentence was imposed
before a state sentence, the BOP may indirectly award credit for time served in state prison by
designating nunc pro tunc the state prison as the place in which the prisoner serves a portion of
his federal sentence.”). But where nothing in the record shows the federal court intended for its
sentence “to run concurrently” with a state sentence, “the BOP [is] well within its discretion to
deny [a] request for a nunc pro tunc designation.” Rodriguez v. Pitzer, 76 F. App’x 519, 520 (5th
Cir. 2003). And while the sentencing court expressed its desire that Shepherd receive credit for
time in custody before his federal sentence was imposed, the judgment was silent as to future
potential state sentences. See Free v. Miles, 333 F.3d 550, 553 (5th Cir. 2003) (“Well-settled
federal law presumes that when multiple terms of imprisonment are imposed at different times,
they will run consecutively unless the district court specifically orders that they run
concurrently.”). The BOP’s refusal to award Shepherd a nunc pro tunc designation does not
entitle him to habeas relief.
Finally, in his reply, Shepherd hints that his state convictions were obtained in violation
of his constitutional rights. Specifically, he says that he picked up the state charges “for
contraband found in a common area” because he was “housed with state inmates despite being
under a federal sentence.” Reply [8] at 3. He argues that “[h]ad he been in federal custody, the
matter would have been a BOP disciplinary infraction, not a new state conviction,” such that
there would be no state sentences to credit with his jail time. Id. Factually, Shepherd was charged
with both state charges before he was sentenced by the federal court, and Shepherd has not
shown he had a right to be held in a federal facility prior to the imposition of his federal
sentence. Regardless, this § 2241 petition challenging the BOP’s calculation of Shepherd’s
federal sentence is not the proper vehicle to challenge the state-court convictions and sentences.
See Rule 2(c) of the Rules Governing Section 2254 Cases in the United States District Courts
(“A petitioner who seeks relief from judgments of more than one state court must file a separate
petition covering the judgment or judgments of each court.”). And in any event, courts typically
do not address matters raised first in replies. See Magnolia Island Plantation, L.L.C. v.
Whittington, 29 F.4th 246, 251‒52 (5th Cir. 2022) (“As a general matter, a district court is not
required to address new legal issues raised only in a reply brief.”).2
III. Conclusion and Recommendation
The Court has considered all arguments. Any not directly addressed would not have
changed the outcome. For the reasons stated, the undersigned recommends the Court deny and
dismiss with prejudice Shepherd’s petition.
IV. Notice of Right to Object
In accordance with Federal Rule of Civil Procedure 72 and 28 U.S.C. § 636(b)(1), any
party, within fourteen days after being served a copy3 of this report and recommendation, may
serve and file written objections to the recommendations, with a copy to the United States
District Judge, the Magistrate Judge, and the opposing party. The District Judge at the time may
accept, reject, or modify, in whole or part, the recommendations of the Magistrate Judge, or may
receive further evidence or recommit the matter to the undersigned with instructions. The parties
are hereby notified that failure to file written objections to the proposed findings, conclusions,
and recommendations contained within this report and recommendation within fourteen days
after being served with a copy shall bar that party, except upon grounds of plain error, from
attacking on appeal the proposed factual findings and legal conclusions accepted by the district
court for which there is no objection. 28 U.S.C. § 636(b)(1); Fed. R. Civ. P. 72(b); Alexander v.
2 Shepherd raises yet another new argument for the first time in his reply. He argues Louisiana’s
“3-for-1” rule means he should have served only three months of his twelve-month sentence on
State Charge #3. Reply [8] at 3. This argument is not properly before the Court. Magnolia Island,
29 F.4th at 251‒52. In any event, Shepherd cites no facts or law to support it, and it isn’t entirely
clear what he is arguing. Presumably he is suggesting that he would have been entitled to good-
time credits under state law. But he fails to demonstrate that he was eligible for good-time credits
or that he earned them. His arguments lack merit.
3 When a document is served by mail, the party is considered to have been served on the date the
document is mailed by the Court. See Fed. R. Civ. P. 5(b)(2)(C).
