The anonymous tipster who led officers to the parents of accused Michigan high school shooter Ethan Crumbley is to reap a reward of up to $ 20,000, a new report says.

“I understand that, and I talked to the sheriff and a few other people about that investigation, and it looks like that tip – the caller will be eligible for the reward,” Detroit Police Chief James White told the Detroit Free Press Sunday. .

“So I’m happy about that,” White said.

The U.S. Marshals Service offered a $ 10,000 reward for information that led to the whereabouts of both parents while James and Jennifer Crumbley hid as prosecutors searched for them in Tuesday’s deadly shooting at Oxford High School.

The tipper could end up with as much as $ 20,000 to help secure both parents, Free Press said.

The couple’s 15-year-old son is being held without bail charged with first-degree murder, terrorism and assault with intent to murder for allegedly killing four students and injuring seven others.

The teenager’s parents bought the 9mm semi-automatic pistol used for the attack and allegedly gave him access to it while they were aware of the boy’s deeply worrying behavior recently.

Authorities had announced that they were charging the parents with involuntary manslaughter in the case and the couple disappeared. Police launched a hunt for them and caught them on Saturday.

The Crumbleys, which was found in the basement of an art studio around noon. 22.30 Saturday, is now being held back against $ 500,000 bail each.

On Sunday, police said they had identified 65-year-old Detroit artist Andrzej Sikora as a person of interest suspected of helping the Crumbleys hide from police.

Sikora has not been charged and it is unclear how he knows Crumbleys.
