It seemed like a routine arrest when police caught four suspects, wanted for robbing two UK students on campus.

Charles Davis, along with two other men and a juvenile, were arrested over the weekend.

But Davis' arrest has a Lexington mother asking questions.

16-year-old Tyler Blauser was killed last year after Davis crashed his car on Man O'War.

Blauser's mother says the teen served time for reckless homicide.

Tonight, Donna Blauser wants to know how he was able to get back behind the wheel so soon.

She lost her son, Tyler Blauser, in this crash on Man O' War. Blauser was riding with four other teenagers, and 16-year-old Charles Davis had only a learner's permit.

Blauser says he was convicted for reckless homicide for the what happened that night, and served time at a juvenile boy's center in Lexington.

He was released in August, and within two weeks, he had a full Kentucky Driver's License and a vehicle.

Then this weekend, police arrested Davis and four others for two separate robberies on UK's campus last month. Davis was allegedly driving the cars at the time of the attacks.

Blauser says she can't understand how Davis got behind the wheel again.

Officials with the Transportation Cabinet say there's no record Davis ever received a new license.

Davis is being held on a $20 thousand full cash bond at the Fayette County Detention Center.
