Casey Doss

Last week, Doss, 19, was arrested and charged with leaving the scene of a car accident. Police said Casey ran off Westwood Drive and hit some trees in an April 9 crash that injured a passenger’s arm. Police later found Doss at his home in the 2700 block of Bromley Drive. They said Doss refused a blood alcohol test.

A year ago, I wrote about Doss, an O’Fallon, Mo., teenager who got into a deadly fight with his dad in February 2008.

Doss, then a senior at Francis Howell High School, had come home late after a night of drinking. His dad, Larry Doss, 58, confronted Casey about a noisy muffler on his car that was disturbing the neighborhood.

They started shoving each other, and both tumbled down the stairs. Casey punched his dad in the head several times.

Larry Doss’ brain began hemorrhaging internally. He had been taking Plavix, a blood thinner designed to prevent heart attacks.

The bleeding wouldn’t stop, and Doss died five days later at the hospital.

After his death, a pathologist with the St. Louis County medical examiner’s office said the drug would explain the large amount of bleeding around Doss’ brain.

Casey was charged with involuntary manslaughter, and in October, pleaded no contest. He was sentenced to five years’ probation for the crime.

In an interview last year, Casey Doss’ mother, Shirley Doss, blamed the attack, in part, on her son’s alcohol abuse.

“He’s just a good kid who made a bad mistake,” she said.

The state filed a motion Friday to revoke Casey Doss’ probation. A hearing to address his probation is set for April 20.
