(WXYZ) — After pleading guilty to all 24 charges brought against him in connection to the mass school shooting at Oxford High School, Ethan Crumbley potentially threw his parent's criminal case in a tailspin.
Durning the pretrail Ethan admits that he gave his father the money to purchase the weapon he used to murder four children.
“is it true you gave him your own money to buy the firearm? Yes. Is it true that you picked that gun out to buy? Yes," he responds to the two questions.
According to retired ATF supervisory special agent Dondald Dawkins, those allegations carry "serious weight behind it. There's a reason that those kinds of purchases are illegal," he said.
Nonetheless, Dawkins says there could be some leeway in this case.
"It's a straw purchase. On face value it is. But sometimes that flies because it's in a home, but it still has to be secured. He bought it for his son, it still has to be secured," he said.
Crumbley admits that it wasn’t.
"Is it true that on November 30, 2021 when you obtained the firearm it was not kept in a locked container or safe? Yes it was not locked," he said.
Linda Watson's son Aiden was shot by Ethan but survived. They were in the courtroom Monday listening to Ethan's claims.
"It's incredibly sad and makes you so angry at the same time. And, it's not over," Watson said.
But a former federal prosecutor tells us Crumbley’s confessions are contradicting his parents and they could be used in their case.
"His statements in a plea hearing itself cannot be used against the parents at their trial because they have the right of confrontation, in other words, to cross-examine him," former federal prosecutor Mark Chutkow said.
Chutkow says it is possible, however, for Crumbley to work with the prosecution and testify against his parents.
“I don't know what they're thinking but certainly, it has to give them pause," he said.
This Friday, James and Jennifer Crumbley will be in court regarding expert witness testimony. Their trial date is set for January 17.
