People v. Ikerman
973 N.E.2d 1008
Ill. App. Ct.2012Background
- Defendant Mark Ikerman was convicted of two counts each of aggravated DUI resulting in two deaths and two counts of failure to report an accident, plus two counts of aggravated driving with BAC 0.08+ resulting in two deaths.
- Evidence showed Ikerman left the crash scene, drove away in a damaged tow truck with no headlights, and subsequently denied intoxication.
- Blood test indicated BAC 0.020 approximately 10 hours after the crash; retrograde extrapolation was used to estimate a BAC around 0.200 at the time of the crash.
- State presented expert testimony supporting retrograde extrapolation; defense challenged reliability and potential contamination but the trial court accepted the State’s expert.
- Trial court merged certain DUI and failure-to-report convictions for sentencing and imposed 10 years on aggravated-DUI counts and 5 years on failure-to-report counts, consecutive.
- Defendant argued insufficient proof of BAC 0.08+, intoxication, proximate cause, and requested probation despite no extraordinary circumstances; the court denied probation.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Sufficiency of BAC proof via retrograde extrapolation | Ikerman challenged retrograde extrapolation as unreliable. | Retrograde extrapolation cannot prove intoxication beyond reasonable doubt. | Sufficiency supported; expert admissible; BAC proven by retrograde extrapolation. |
| Intoxication at time of crash | Proved intoxication through BAC and related evidence regardless of signs. | No direct signs of intoxication required for 0.08+; strict liability applies. | Evidence supports intoxication at time of crash; conviction upheld. |
| Proximate cause of deaths | DUI/0.08+ driving was proximate cause of deaths. | Driver’s actions not the sole cause; other factors implicated Legens vehicle position. | Sufficient evidence to establish proximate cause beyond reasonable doubt. |
| Probation/extraordinary circumstances at sentencing | Probation may be justified if extraordinary circumstances exist. | Defendant presented mitigating factors and extraordinary circumstances. | No extraordinary circumstances; probation denial affirmed; sentence not an abuse of discretion. |
