A 16-year-old Lawrence boy who crashed his mother’s Porsche into a tree last week has been released from a Topeka hospital and also received two traffic citations for speeding and driving without a valid license, according to an accident report.

According to a Douglas County Sheriff’s office report released Friday, a deputy talked with the driver, Joshua W. Boisen, at his home Thursday night. Boisen told the deputy he suffered six broken ribs and a ruptured spleen in the one-vehicle crash. It occurred at 3:50 a.m. Dec. 23 at the intersection of East 1100 and North 1700 roads just northwest of Lawrence. The intersection is an extension of Folks and Peterson roads.

Boisen also told the deputy he took his mother’s 2012 Porsche Carrera without her permission at approximately 3 a.m. Dec. 23. He traveled to his father’s house in northern Lawrence. About 45 minutes later he was driving west on North 1700 Road and turned south onto East 1100 Road at a high rate of speed. After he completed the turn, he decided to turn around and travel north through the curve again, but he lost control of the vehicle and struck a tree. He was eventually flown to Stormont-Vail Regional Health Center in Topeka.

The report lists driver inattention and reckless or careless driving as contributing factors. Officers found no evidence of impairment.

According to the accident report, when police notified his mother, Melissa Boisen, at her home the morning of the accident, she said she believed her car was in the garage and that nobody had permission to have it. She also said her son did not have a valid driver’s license.
