Michigan school shooter Ethan Crumbley's parents drained $3K from his bank ...

Michigan high school shooter Ethan Crumbley's parents drained his bank account and made plans to move to Florida where they planned to sell horses immediately after he was arrested for killing four classmates, a court heard. 

James and Jennifer Crumbley appeared in court on Friday where they asked a judge to lower their $500,000 bond to $100,000. But that request was denied by an Oakland County judge who deemed that both parents were a flight risk. 

The parents are charged with manslaught in connection to the November 30 massacre at Oxford High School where four students were killed. The Crumbley's ignored numerous warning signs about their 15-year-old son and instead bought him a gun that was used in the shooting, assistant prosecutor Marc Keast told a judge. 

The pair are also accused of refusing to take him home earlier that day when school counselors confronted them with distressing drawings he made, including that of a gun and blood on the floor. 

They then went on the lam for two days, December 3 and 4, after he was arrested and withdrew $3,000 from his bank account, leaving only 99 cents. 

At Friday's hearing, the judge rejected the argument by attorneys Mariell Lehman and Shannon Smith that the Crumbley parents had enough ties to the community that a reduced bond would be enough to keep them in Michigan.

During Friday's bond hearing, Prosecutor Karen McDonald argued that the bond should remain at $500,000 for each of them because of their lack of ties to the state of Michigan and their plans to flee the area just hours following their son's arrest.   

McDonald said James, who worked as a Doordash delivery driver and Jennifer, who had been terminated by her employer, both had families in Florida and started making plans to move there immediately after the shooting.

'On November 30, just hours after their son murdered children in a school, they started making plans.,' McDonald told the court. 

She added that they started making plans to sell horses once they were in Florida and bought four cellphones. They had also drained their son's bank account of $3,000, leaving only 99 cents.

On December 1, the couple checked into a different hotel where they made contact with discussion of the sale of their horses and withdrew $2,000 from their bank. They then checked out of the hotel,  leaving one of their cars behind but parked so that the license plate could not be easily seen. 

McDonald said they drove to the art studio in Detroit the same day where they were captured and taken into custody after leading authorities on a large-scale manhunt.

Both Crumbleys have pleaded not guilty to all four charges of involuntary manslaughter - one for each Oxford High School student. Each count is punishable by up to 15 years in prison along with a $7,500 fine and mandatory DNA testing. 

Earlier on Friday, their son waived a key hearing, a decision that moves his case straight to a trial court.
