Lake County Coroner Howard Cooper has released the preliminary cause of death for 17-year-old Abe Gonzalez of Island Lake.

Cooper completed an autopsy on the teen Friday and said Saturday that preliminary results indicate Gonzalez died from drowning. There were no signs of foul play on his body, and toxicology results still are pending, the coroner said.

“The investigation into his death continues by our office and the Lake County Sheriff’s Office,” Cooper said in a statement. “We have been in close contact with Abe’s family, and our deepest condolences go out to them during this difficult time.”

Sheriff’s detectives and auxiliary deputies found Gonzalez dead Friday morning in a swampy area near Slocum Lake in Wauconda, according to the Lake County Sheriff’s Office. Deputies found the body submerged in about a foot of icy water in a swampy area near the lake.

Gonzalez was seen by his father walking out the front door of his home in Island Lake on Nov. 1 wearing a gray hoodie, blue jeans and white shoes. He last was seen walking west on Maple Avenue in unincorporated Lake County, police have said.

According to the Island Lake Police Department’s Facebook page, Gonzalez said he was going out to get some fresh air. Later that evening, Gonzalez was seen at a home in the 26000 block of Morey Street attending a party in unincorporated Lake County.

He then was seen leaving that house on foot by himself about midnight Nov. 2. Gonzalez’s father notified Island Lake police of his son’s disappearance at 6:35 p.m. Nov. 2 after Gonzalez failed to return home.
