Opinion
Clifford Lamar Jackson appeals from a judgment of imprisonment which was rendered after a jury found him guilty of two counts of forcible rape (Pen. Code, § 261, subd. 3) and two counts of forcible oral copulation (Pen. Code, § 288a). Two victims were involved on occasions two days apart.
Appellant contends that the trial court should have dismissed the charges connected with one of the victims because investigative officials failed to preserve semen specimens taken from the victim at a hospital after the rape. Comparison of genetic markers found in the semen specimen with those in an innocent man’s blood might have afforded an innocent individual a high probability of scientific exculpation. Appel *623 lant had moved for production of the semen specimens but the district attorney advised the court that the evidence no longer existed.
Appellant contends that

Hitch

Included in the record in the present case is a property receipt signed by a police officer, indicating that “vaginal cotton swabs” in police custody had been stored at the medical laboratory at Fort Ord. The specimens were lost, and there was no showing that reasonable measures had been taken to preserve the evidence. The question is thus presented whether loss of the evidence compels reversal of the judgment. The Supreme Court did not consider that question in

because there the prosecution had delivered the specimen to the defense in response to discovery and there was no showing that deterioration of the specimen was caused by the state’s inaction. We therefore return to
Hitch
for guidance as to the effect to be given to the apparent failure of the police to preserve the specimen. According to
Hitch
the ordinary remedy is the exclusion of test results; it is said that dismissal “may well be the proper sanction” where there has been bad faith on the part of the prosecution (
The trial court denied a defense motion to sever the two sets of charges. Penal Code section 954 provides that where an accusatory pleading charges two or more different offenses of the same class of crimes or offenses the trial court, “in the interests of justice and for good cause shown, may in its discretion order that the different offenses or counts set forth in the accusatory pleading be tried separately....” In denying the motion for severance, the trial court stated: “I don’t know of any authority that stands for the proposition that you can sever the same class of crimes based upon the fact they are not similar... so, without authority I am aware of, the motion has to be denied.” It thus appears that when the court denied the motion for severance it was acting under an erroneous belief that it had no authority to grant the motion.

v.
Rist
(1976)
Appellant contends that the nondiscretionary denial of severance was prejudicial because it permitted the prosecution to use evidence of one rape to prove lack of consent in the other and to use evidence of the second rape to prove the identity of appellant as the perpetrator of the first. But if the charges had been severed, in each trial the evidence of the uncharged offenses would have been admissible as relevant to prove a fact other than a disposition to commit such acts. (See, e.g.,

v.
Beamon
(1973)
*625
Where a primary issue of fact is the identity of the defendant as the perpetrator of the crime, as in one of the sets of offenses in the present case, evidence of uncharged offenses is ordinarily admissible if it discloses a distinctive modus operandi common to both the charged and uncharged offenses. The modus operandi gives rise to a reasonable inference that both the offenses were committed by the same person if the marks common to those offenses set them apart from other offenses of the same general variety.
(People
v.
Matson
(1974)
Common marks accompanied the two sets of offenses. In each case the assailant grabbed the victim’s head or neck in his arm, dragged her some distance, slapped her repeatedly, threatened to kill her, ordered her to “suck my dick” or “suck my cock,” and subsequently forced sexual intercourse. While the modus operandi so far described may be shared by a number of other cases of sexual assault, there is an additional feature of the two sets of offenses whose distinctive nature tends to differentiate these offenses from other sexual assaults. In each case the assailant attempted to be friendly to his victim after he had raped her, lingering to make conversation with the victim and expressing concern for her wellbeing (“Take care of yourself, Sue” and “If anybody fucks around with you, come to me. My name is Clifford”) and then simply walking away from the victim. A single distinctive common mark considered in combination with other common but undistinctive marks may invest the evidence of uncharged crimes with probative value sufficient to outweigh its prejudicial effect. (See People v. Haston, supra, 69 Cal.2d at pp. 247-250.) The combination of distinctive and undistinctive common marks in the present case was sufficient to give rise to a reasonable inference that the charged and uncharged offenses were committed by the same person.
As to the other set of offenses, where the defense claimed consent, evidence of a prior sex offense involving a victim other than the prosecuting witness was admissible to corroborate the prosecutrix’ testimony where the prior offense was not remote in time, was similar to the charged offense, and was committed upon a person similar to the prosecuting witness.

If the two sets of charges had been severed, in each trial the evidence of the uncharged offenses would have been admissible. The court’s misapprehension in denying the motion for severance thus did not prejudice appellant. (See

The judgment is affirmed.
