Charlie Tan, who once stood accused of killing his father, pleaded guilty to federal gun charges on Friday.

However, Tan did not admit to killing his father.

Tan changed his plea at a hearing in Syracuse at 3:30 p.m.

Tan had previously pleaded not guilty to accusations he had had a friend illegally buy a shotgun to be used to kill Charlie's father, Jim Tan.

According to paperwork, in February of 2015 Charlie Tan had fellow Cornell student Whitney Knickerbocker purchase the Remington shotgun at a Cortland County Walmart.

Ballistics testing later confirmed that this was gun used to kill Jim Tan.

According to the appellate court, the judge wrongly dismissed the case after a hung jury.
