ST. LOUIS – St. Louis Cardinals pitcher Josh Hancock was drunk and talking on his cell phone at the time of his fatal accident, and marijuana was found in the sport utility vehicle he was driving.

Medical examiner Michael Graham said at a news conference Friday that the 29-year-old reliever was dead “within seconds” from head injuries in the crash early Sunday on Interstate 64 in St. Louis. His vehicle hit the back of a tow truck parked on the highway to assist a driver from a previous accident.

“There is nothing at all that could have been done for him,” Graham said.

Hancock’s blood-alcohol level was 0.157, nearly twice Missouri’s legal limit of 0.08, Graham said.

Police Chief Joe Mokwa said 8.55 grams of marijuana and a glass pipe used to smoke marijuana were found in the rented Ford Explorer. Toxicology tests to determine if drugs were in his system had not been completed.

An accident reconstruction team determined Hancock was traveling 68 mph in a 55 mph zone when his SUV struck the back of a flatbed tow truck stopped in a driving lane. Mokwa said there was no evidence Hancock tried to stop. He did swerve, but too late to avoid the collision.

Hancock was not wearing a seat belt, but Graham said the belt would not have prevented his death.

Graham said the pitcher died instantly of head injuries. The pitcher was not wearing a seat belt, but Graham said the belt would not have prevented his death.

Mokwa said cell phone records showed Hancock was speaking with a female acquaintance at about the time of the accident. Mokwa said the conversation ended abruptly, presumably when the accident occurred.
