Authorities say that Michelle Roenz was found dead in the trunk of a car driven by her 17-year-old son, Tyler

A Texas teenager has been arrested after authorities say they found him driving through Nebraska with his mother's body in the trunk of his car.

Tyler Roenz, 17, and his 49-year-old mother Michelle Roenz were reported missing on Thursday. According to documents obtained by ABC-13, Tyler's father contacted police after he found blood and a human tooth in the garage of their home in Humble, Texas.

Tyler's father then followed a trail of blood into the master bedroom, where he allegedly found four additional human teeth in a pool of blood.

Surveillance footage allegedly shows the family's Mazda 3 leaving the house at 11:44 a.m. on Thursday.

According to court documents, which were also obtained by Click2Houston.com, Michelle Roenz's credit card was used in Texas and Kansas, allegedly en route to Nebraska. The car's license plate was also pinged on a radar near Dallas, Texas.

Based on the evidence, authorities figured out that the car was likely heading northbound. They alerted authorities in Nebraska to be on the lookout for the Mazda. When the Nebraska Highway Patrol spotted the vehicle and attempted to stop it, the driver allegedly fled.
