Last week, the Onondaga County Sheriff’s Office added a new “unsolved crimes” section to its website and Facebook page, and specifically focused on the April 21, 2008 murder of village of Liverpool resident Mark A. Clark.

Clark’s body was discovered that Monday morning by his father, Harry Clark, in the bedroom of the house Mark rented at 109 Cleveland St., in Liverpool. A toy collector who was raised in the village, Mark Clark was just four days shy of his 40th birthday.

Harry Clark, who has since passed on, told neighbors that his son had died from a shotgun blast.

Although the crime was committed three years and four months ago, no arrests have been made.

“We’re still looking for the public to provide some information to help us solve this crime,” said Sheriff Kevin Walsh said on Aug. 17. He hopes potential witnesses will respond online.

“Eventually there will be a number of unsolved cases listed up there,” Walsh added.

“We have no suspects [in the Clark killing],” Walsh said in an April interview with the Star-Review. “We know the cause of death – it was a single gunshot wound – now it’s the who and the why, and we’re working diligently to determine those.”

Dozens of Clark’s associates were interviewed by sheriff’s investigators, Walsh said.

Clark had once been married and had a son, but the marriage ended. A live-in girlfriend had reportedly moved out of the Cleveland Street house a few months before the murder. Investigators talked with her, Walsh said, but she offered no useful information.

Anyone with information about the murder can call deputies at 435-3081, e-mail [email protected], or call the Liverpool Police Department at 457-0722, where Det. Michael Lemm is assigned to the case.

The sheriff’s online effort “is a step in the right direction,” Lemm said.
