Pleasanton police are investigating after a body was discovered near the Marilyn Murphy Kane Trail on Thursday evening.

The decedent had not been identified yet and investigators were still at the scene as of midmorning Friday.

"We are in the early stages of this investigation and at this point, it is unknown if there was any foul play involved," Lt. Erik Silacci said in a statement.

The initial discovery was made around 5:30 p.m. Thursday, after the Pleasanton Police Department received a report about a body near the eastern end of the Marilyn Murphy Kane Trail in the southwestern part of the city.

Officers responded and confirmed that the person -- who was male -- was deceased, according to Silacci.

Detectives are also still trying to determine the circumstances of the death. PPD's criminal investigations unit was still at the scene as of 9:30 a.m. Friday, as well as receiving assistance from the Alameda County Sheriff's Office crime lab and coroner's bureau, according to Silacci.

Silacci told the Weekly on Friday afternoon that many key questions were still pending, including the victim's identity, his cause of death and how long he'd been dead before his body was discovered.

"We will hopefully have an update next week, assuming the coroner is able to identify the body by then," the lieutenant said. "We will have a better idea after the coroner completes their report(s)."
