Did a Downriver man suffer a leg cramp 35 years ago, or did he murder his four young children?

In August of 1989, Larry DeLisle drove a station wagon with his wife and four children in it into the Detroit River, killing the kids. On a new Daily J On The Case, WWJ's Christy Strawser and Zach Clark explore whether he had a leg cramp and a deficient car, or if he's a cold-blooded killer. (PHOTO: Fox 2 Detroit/YouTube)
