Suspect’s Criminal History

Striblin has been previously convicted for a drug offense and evading arrest, Texas court records show.

In October 2006, Striblin pleaded guilty to evading arrest and received a six-month jail sentence, according to records.

Less than two years later, he again pleaded guilty to evading arrest and was sentenced to serve two years.

In 2014, Striblin entered a plea of no contest to possession of a controlled substance and was placed on community supervision on a deferred adjudication, records show. He pleaded guilty to a second count of the same charge.
