A second teenager has been charged with the murder of Stephen Cobb.
The December grand jury indicted 19-year-old William I. Keyes, 1000 block of W. Market St., for murder, involuntary manslaughter, aggravated robbery and felonious assault with specification.
Last week police charged Michael Anthony McGee, 15, with murder.
Cobb, 29, was found unconscious in a pool of vomit Oct. 6 at McDonough and Water streets. He was taken to The University of Toledo Medical Center, where he was died eight days later.
In the preliminary autopsy results released Wednesday, a Lucas County deputy coroner ruled Cobb died as a result of traumatic brain injuries from an assault.
A half-inch-long laceration was on the back of Cobb's head when he arrived at the hospital in Toledo, according to the autopsy summary.
"We don't know if there was a weapon used," said Kevin Baxter, Erie County prosecutor.
The motive for the attack on Cobb seems to be money-related, he added. So far no money has been confiscated by police as evidence, Baxter said.
Meanwhile, the legal process to charge McGee as an adult has already begun, according to Baxter.
Police are checking into reports Cobb stole a woman's cell phone Sept. 17 to see if that report is connected to the assault on him.
A full autopsy report on Cobb has yet to be released pending an ongoing investigation, he said.
Keyes had no prior arrest record with Sandusky police. He has been in the Erie County jail on a $35,000 bond since Oct. 19.
