¶1Defendant Michael P. Gavin appeals from his jury conviction of murder in the first degree, Iowa Code section 707.2 (1981), kidnapping in the first degree, section 710.2, and theft in the second degree, section 714.-2.
¶2I. Cross-Examination of Defendant about Prior Escape Conviction.
¶3The defendant had been convicted of escape in 1974. The record does not indicate the details of the offense. Over defense counsel’s objection, the trial court permitted cross-examination of the defendant about the escape conviction. On appeal, he contends the trial court erred in allowing this impeachment testimony because escape does not involve dishonesty or false statement, and under the rule of State v. Martin, 217 N.W.2d 536 (Iowa 1974), was therefore inadmissible.
¶4We have recently reviewed the principles applicable to use of a prior felony conviction to impeach a defendant. See State v. Zaehringer, 325 N.W.2d 754 (Iowa 1982). In Zaehringer, the defendant was charged with rape; we held, based on the guidelines laid down in Martin, that the trial court erred in allowing impeachment of the defendant by a prior felony conviction for delivery of marijuana.
¶5To be admissible, evidence of a prior conviction must meet a two-pronged test: (1) the prior crime must involve dishonesty or false statement, and (2) the trial court must determine that the danger of unfair prejudice does not substantially outweigh the probative value of the conviction. Zaehringer, 325 N.W.2d at 756; State v. Conner, 241 N.W.2d 447, 454 (Iowa 1976); Martin, 217 N.W.2d at 542.
¶6We have used the “elemental” test to determine whether specific categories of crimes met the Martincriteria of dishonesty. In Zaehringer, for example, we examined the elements of the crime of delivery *503of marijuana, found that none of them were couched in terms implying deceit, fraud, cheating or stealing, and concluded a conviction for that crime was not admissible. Zaehringer, 325 N.W.2d at 756.
¶7In Iowa, escape may be committed in a number of ways, and the elements vary accordingly. Under Iowa Code sections 719.4(1) or (2), escape is committed if a person, charged or convicted of a crime, “intentionally escapes from any detention facility or institution to which the person has been committed.” A misdemeanor escape is committed under section 719.4(3) if a person absents himself from any place where he is required to be, or flees from the state to avoid prosecution, under section 719.4(4). While dishonesty in the form of deception or ruse might actually be present in some escape cases, this is not an element expressly or impliedly required by any of the various forms of escape under Iowa Code section 719.4.
¶8Under analogous rules, other jurisdictions have not permitted impeachment for escape or similar offenses. See, e.g., United States v. Frazier, 418 F.2d 854 (4th Cir.1969) (per curiam) (conviction for being absent without leave inadmissible to impeach government witness because not a “felony, infamous crime, petty larceny or a crime involving moral turpitude”); United States v. Tomaiolo, 249 F.2d 683, 692 (2nd Cir.1957) (A.W.O.L. offense not a felony or crime involving moral turpitude and could not be used for general attacks on credibility); Munsey v. State, 496 S.W.2d 525, 527 (Tenn.1973) (same); Cox v. State, 50 Ala.App. 339, 341, 279 So.2d 143, 143 (1973) (same).
¶9We hold the trial court committed reversible error in allowing impeachment based on the felonious escape. At this joint trial, the defendant’s credibility was critical to the success of his defense, especially in light of the testimony of one of the co-defendants that the defendant had threatened or coerced him to become involved in the crime. Under these circumstances, we cannot find the error was harmless. See Zaehringer, 325 N.W.2d at 758.
¶10II. Other Issues.
¶11We have considered the remaining issues presented. Issues (1) and (2) would not arise on re-trial and do not warrant discussion. With regard to issue (4), we conclude the defendant’s argument is without merit. See Iowa Code § 707.2(2) (felony murder); see also 40 C.J.S. Homicide § 21 at 868 (1944) (person killed need not be person robbed).
¶12The judgment of the trial court is reversed, and the case is remanded for a new trial.
¶13REVERSED AND REMANDED.
¶14All Justices concur except CARTER, J., who dissents.
¶15. The facts surrounding these crimes are not specifically detailed as they have been set forth before in the separate appeals of two other co-defendants, see State v. Schertz, 328 N.W. 2d 320 (Iowa 1982) and State v. LeCompte, 327 N.W.2d 221 (Iowa 1982).
