SHERIDAN, Wyoming (CBSDFW.COM/AP) — Wyoming authorities said a Texas man suspected of drunken driving is dead after jumping out of his speeding vehicle while being chased by a state trooper.

The Wyoming Highway Patrol said 43-year-old Marshall Acker of Tyler climbed out of his vehicle through his sunroof during Friday’s chase and jumped onto Interstate 90 near Sheridan as his vehicle traveled at around 80 mph.

The approximately 5-mile pursuit started after troopers were notified of a suspected drunken driver. Acker was initially spotted driving at 97 mph in a 75 mph zone and failed to stop for a trooper who turned on his emergency lights and sirens.
