Autopsy: Fatal stabbing victim had methamphetamine in system

CHICAGO (AP) - Autopsy results show a Chicago man who was slain in the apartment of a Northwestern University professor last month had methamphetamine in his system at the time.

The Cook County medical examiner's office on Friday released the findings in the death of Trenton Cornell-Duranleau. The 26-year-old hair stylist's body was found July 27. He was stabbed dozens of times.

Fired Northwestern University microbiologist Wyndham Lathem and Oxford University financial officer Andrew Warren are accused in Cornell-Duranleau's death.

Authorities have said the attack on Cornell-Duranleau, a Michigan native who moved to Chicago last year, was so brutal that the blade of the knife investigators believe was used in the stabbing was broken.

Authorities have offered little information about what may have led to the attack. But a Chicago police spokesman said Lathem had some sort of relationship with Cornell-Duranleau.

The two suspects fled on a cross-country odyssey and surrendered to authorities in California on Aug. 4.
