A 13 year old cold case in Huron has been solved.

Police say the remains Heath Styer have been identified in a car pulled from "Lake Ravine" last week.

Styer was 25 years old when he disappeared on his way to meet his girlfriend at the lake.

But until tonight...no one knew for sure what happened to him.

Last week, a make-shift memorial was set up in Heath Styer's honor along Lake Ravine.

It's the latest chapter in a mystery that's spanned 13 years.

That memorial appeared not long after divers pulled Styer's 1990 Chevy Beretta from 12 feet of water.

Styer was last seen in the early hours of June 26, 1995 when a Huron Police officer saw Styer's car speed down Highway 14.

Police had searched Lake Ravine before...but had no luck.

South Dakota Game, Fish and Parks used a newly purchased side sonar system that led to the discovery of Styer's car.

But investigators said it would take some time to determine if remains were in the car...because of silt and mud that accumulated inside.

Some friends and neighbors say they've always believed Styer was in the lake...somewhere.

But until tonight...no one knew for sure.

Authorities used dental records to identify Styer and say there were no signs of foul play.

Investigators say they're still trying to piece together *how* his car ended up in the lake.
