Fayetteville, NY -- A DeWitt woman whose body was found Saturday floating at Green Lakes State Park is believed to have committed suicide, Onondaga County District Attorney William Fitzpatrick said.

The victim, who went by the name Sarah, 38, was born Paul Kench Jr., Fitzpatrick said today. New York State Park Police also today confirmed the identity of the person found in the lake.

The investigation showed she handcuffed herself to a mountain bike before driving into Green Lake. Fitzpatrick said. A handcuffs' holder was attached to her belt and the key for the handcuffs was in the holder, he said.

Kench also left a written suicide note in which she apologized to her family and predicted her body would never be found, the DA said.

The victim apparently died more than a week ago, said Senior Assistant District Attorney Rob Moran. He did not have any more specific information about the exact day or time.

Fitzpatrick said he didn't know if the woman's gender identity had anything to do with her apparent suicide.

The cause of death was drowning, according to a news release the New York State Park Police issued today.

A park visitor reported to 911 at about 12:30 p.m. on Saturday that she saw what appeared to be a body floating in the lake. At approximately 1 p.m., Fayetteville Fire Department personel recovered the body from the lake.

The body was found on the west side of the lake between the beach and the connecting trail to Round Lake. That section of the trail was closed to the public for about 24 hours as police investigated the death.
