Parents of Michigan school shooting suspect are held on $500,000 bond after manhunt. After an hours-long manhunt led to their arrest overnight in Detroit, the parents of the 15-year-old boy accused of fatally shooting four students at a high school in Michigan have pleaded not guilty to involuntary manslaughter charges connected to the deaths.

At an arraignment Saturday morning, lawyers for Jennifer and James Crumbley denied that the pair had fled law enforcement. Instead, they said, the couple had intended to voluntarily appear for arraignment Saturday — a characterization that Michigan authorities appeared skeptical of.

"This case is the saddest, most tragic, worst case imaginable. There is absolutely no doubt that our clients were going to turn themselves in, and it was just a matter of logistics," Shannon Smith, a lawyer representing the pair, said during the arraignment.

A judge has set their bond at $500,000 each. Both parents face four counts of involuntary manslaughter related to the mass shooting in Oxford, Mich., about 40 miles north of Detroit. Each count is punishable by up to 15 years in prison.
