POLKTON TOWNSHIP, Mich. (WOOD) — The body pulled from the Grand River near Coopersville over the weekend is that of a Grand Haven-area man who went missing in November.

The Ottawa County Sheriff’s Office said Monday that an autopsy had confirmed the body is that of Thomas Kasack, 36.

“The main discovery today is that it was not foul play suspected in that incident; no further threat to the public,” sheriff’s office Capt. Jake Sparks told News 8.

The body was spotted in the river near Leonard Street and 68th Avenue in Polkton Township, between Allendale and Coopersville, just before 6 p.m. Saturday. Divers soon removed the body from the water.

Kasack had has been seen alive Nov. 12, walking down Lake Michigan Drive near 48th Street in Allendale Township. He was reported missing the next day. Authorities had gone looking for him, including calling in a Michigan State Police helicopter, since then but didn’t find him.

“Hopefully there is some closure there now,” Sparks said.

He said Kasack was from Grand Haven Township but had been homeless in the months before he disappeared.

Authorities continue to investigate Kasack’s death. Anyone with information is asked to call the Ottawa County Sheriff’s Office at 616.738.4000 or Silent Observer at 877.887.4536.
