CHICAGO (AP) -- Abraham Lincoln has made cameo appearance at the Drew Peterson trial.
As proceedings began Thursday, the judge announced in court that he's received a letter from an inmate in Illinois who claims to have information about a link between the former police officer's murder trial and the 16th president's assassination.
Judge Edward Burmila says the unnamed inmate wrote that the judge should communicate with him if he wants more details. The judge prompted laughter as he deadpanned, "I won't be communicating with him."
Peterson has pleaded not guilty to murder in the 2004 death of his third wife, Kathleen Savio. Authorities charged him only after his fourth wife, Stacy Peterson, vanished in 2007.
The trial at a county courthouse in suburban Chicago is in its seventh day of testimony.
