Background
Richard Lee Coleman, Jr. operated drug houses in Pontiac, Michigan, where he trafficked drug-dependent women and subjected them to sexual violence. Prosecutors charged him with first-degree criminal sexual conduct (CSC-I), two counts of third-degree criminal sexual conduct (CSC-III), three counts of participating in a human trafficking enterprise, accepting the earnings of a prostitute, and maintaining a drug house. A jury convicted him on all counts, and the trial court sentenced him as a fourth-offense habitual offender to, among other terms, 75 to 120 years for the CSC-I conviction.
At trial, the prosecution presented two expert witnesses: Dr. Carl Christensen, an addiction-medicine physician, who explained how drug addiction compromises the frontal cortex and creates powerful incentives for addicts to remain in situations that supply drugs; and Lieutenant Edward Price of the Michigan State Police, who testified about the structure and methods of sex-trafficking operations. Defense counsel did not object to either expert’s testimony at trial, raising challenges only in post-trial motions.
On appeal, Coleman argued that both experts improperly invaded the province of the jury by effectively opining on his guilt, that the trial court erred by omitting a specific unanimity instruction on the “personal injury” element of CSC-I, and that the trial court made multiple errors in scoring the offense variables (OVs) used to calculate his sentencing guidelines range.
The Court’s Holding
The court affirmed all of Coleman’s convictions. It held that Dr. Christensen’s testimony was proper expert opinion — he explained addiction’s neurological effects and why addicts remain in drug-supplying environments without opining on Coleman’s guilt or the legal elements of the charged offenses. As to Lieutenant Price, the court found that portions of his testimony did cross the line by effectively declaring Coleman a sex trafficker and opining on the force-or-coercion element, and that defense counsel performed deficiently in failing to object. However, the error was harmless: the victims’ own testimony, Coleman’s admissions, and financial records provided overwhelming independent evidence of trafficking, such that there was no reasonable probability the outcome would have differed without Price’s offending statements.
On the unanimity instruction, the court held that no specific instruction was required because the alternative definitions of “personal injury” under MCL 750.520a(n) — including bodily injury and mental anguish — are not distinct offenses requiring independent jury unanimity, and the victim’s testimony amply supported both physical and psychological harm.
On sentencing, the court found two scoring errors. The trial court improperly assessed 50 points under OV 7 (aggravated physical abuse) by relying on conduct — Coleman’s second assault in the victim’s bedroom — that occurred after the completion of the CSC-I offense. It likewise erred in assessing 15 points under OV 8 (asportation/captivity) on the same basis. These two errors totaled 65 points, enough to reduce the guidelines range from Level VI (270–900 months minimum) to Level V (225–750 months minimum), entitling Coleman to resentencing on the CSC-I conviction.
Key Takeaways
- Expert testimony on addiction’s neurological effects and general sex-trafficking methodology does not invade the jury’s province so long as the expert stops short of opining on the defendant’s guilt or the specific legal elements at issue.
- Where an expert does improperly offer what amounts to a legal conclusion on guilt, the error is subject to harmless-error analysis; strong independent evidence of guilt can render the error non-prejudicial even when trial counsel failed to object.
- Michigan’s offense-variable scoring rules are offense-specific: conduct occurring after the completion of the sentencing offense cannot be used to score OV 7 or OV 8 unless the applicable statute expressly extends its scope beyond the offense itself.
- Scoring errors totaling 65 points — reducing the defendant’s guideline range by one level — are sufficient to require resentencing under Michigan law.
Why It Matters
This decision reinforces the boundary Michigan courts draw between permissible expert “profile” testimony and impermissible testimony that crosses into legal conclusions about a defendant’s guilt. Prosecutors and defense counsel in trafficking and sexual-assault cases must carefully scope expert testimony to avoid — or timely challenge — opinions that effectively direct a verdict. The case also illustrates that even where such testimony is erroneously admitted without objection, a conviction will stand if the remaining evidence is overwhelming.
On the sentencing side, the opinion is a useful reminder of Michigan’s strict offense-specific approach to OV scoring: the temporal boundary of the “sentencing offense” is a hard limit for most variables, and courts may not bootstrap post-offense conduct into a higher score simply because the same victim was involved. Defense counsel should scrutinize scoring worksheets for this error, particularly in cases involving sequential acts of violence or sexual assault.
