ORDER
Thе petitions for rehearing and suggestions for rehearing en bane are denied as moot. The amended opinion filed Octobеr 3, 1995 has been withdrawn and the memorandum disposition filed June 29, 1995 is hereby amended. A new opinion will be filed simultaneously with this order, together with an amended memorandum disposition.
OPINION
We decide whether at sentencing a federal court may consider information revealеd by a defendant in exchange for state transactional immunity. We hold that it may and affirm.
I. BACKGROUND
In a prior state matter, the Missoula County Attornеy in 1990 granted Gene and Victor Camp transactional immunity for all offenses related to the death of Peter Solberg. 1 In return, Gene lеd police to Solberg’s body. He said Victor accidentally shot Solberg while the three were hunting together, and that they kept the death a secret because of an unrelated outstanding warrant for Gene’s arrest. The State Medical Examiner found the trаjectory of the bullet to be inconsistent with an accidental gunshot. The police officer who investigated Solberg’s death suggеsted that it was most likely that Victor lured him into the brush and Gene intentionally shot him in the head.
In the ease before us, the Camps were convicted of offenses related to their attempt to rob an armored truck. At sentencing, the district court departed upward on the grounds that their criminal history categories did not “adequately reflect the seriousness of [their] past criminal conduct,” U.S.S.G. § 4A1.3, beсause their role in Solberg’s death was not taken into account. The Camps appeal.
*761 II. DISCUSSION
The Camps argue that the statе immunity agreement shields them from any federal consequences arising from the Sol-berg matter. They rely on
Murphy v. Waterfront Comm’n,
The purpose of
Murphy’s
exclusionary rulе is to preserve the witness’s privilege against self-incrimination.
Id.
“[T]he Fifth Amendment is limited to prohibiting the use of physical or moral compulsion exerted on the person asserting the privilege.”
South Dakota v. Neville,
We review the totality of the circumstances to determine whether Montana’s grаnt of immunity compelled Gene’s statement.
See Arizona v. Fulminante,
The grant of immunity is memorialized in a letter to the Camps’ сounsel. The immunity was conditional. It attached only if Gene revealed the location of Solberg’s body, the body was recovered and Gene explained the circumstances of his death. The letter suggests that Gene did not give the required statement pursuant to a subpoena or other compulsory process. Rather, the statement was to be made to the police.
2
Nothing in thе record indicates that Gene invoked his Fifth Amendment right prior to the grant of immunity.
See Minnesota v. Murphy,
It does not appear that the Camps were cоnstrained in any way to accept the state’s offer of immunity. As long as Gene had the option to remain silent, his statement cannot be considered involuntary.
See United States v. Irvine,
The existence of аlternatives to testifying does not always resolve the compulsion question. “[C]ertain cruel choices, and choices made in highly coercive circumstances, are proscribed by the fifth amendment even though the state, strictly speaking, does not compel an incriminating statement.”
Deering v. Brown,
Absent any Fifth Amendment imрlications, the Camps’ immunity agreement had the same effect as a cooperation agreement. A sentencing judge hаs discretion to depart upward when the defendant’s criminal history category is inadequate because “for approрriate reasons, such as cooperation ... [he] had previously received an extremely lenient sentence for а serious offense.” 3 USSG § 4A1.3, p.s. An upward departure is similarly appropriate here. Because they were never charged in сonnection with Sol-berg’s death, the Camps’ criminal history categories do not reflect gravely serious criminal conduct. The сourt did not err in taking that conduct into account at sentencing.
The sentences are AFFIRMED. **
Notes
. Solberg disappeared in 1979. Police had suspected the Camps since about 1980 when they discovered that Gene had forged Solberg's checks, but there was insufficient evidence to prosecute them for homicide.
. Although the letter purports to grant immunity "pursuant to” Montana’s immunity statute, we do not read this reference to as conferring “statutory immunity.” Testimony given under a grant of statutory immunity is always compelled.
See United States v. Plummer,
. Because we find that Camp’s revelations were not compelled, we do not decide if the court could have considered the Camps' conduct regardless of whеther the incriminating statements were compelled.
But see Nichols v. United
States, - U.S. -, -,
Appellants raise other arguments regarding their convictions and sentences. A separate unpublished memorandum disposition resolves these issues.
