(CNN) Los Angeles Angels pitcher Tyler Skaggs died by choking on vomit after using drugs and alcohol, according to the Tarrant County, Texas, medical examiner's office.

High levels of opioids, including fentanyl, oxycodone and oxymorphone, were found in his system, as well as alcohol, according to toxicology results. The death was an accident, according to the autopsy.

Skaggs, 27, was found dead at a Hilton hotel in Southlake, Texas, on July 1. The autopsy was performed the following day.

"We are heartbroken to learn that the passing of our beloved Tyler was the result of a combination of dangerous drugs and alcohol. That is completely out of character for someone who worked so hard to become a Major League baseball player and had a very promising future in the game he loved so much," Skaggs' family said in a statement.

"We are grateful for the work of the detectives in the Southlake Police Department and their ongoing investigation into the circumstances surrounding Tyler's death. We were shocked to learn that it may involve an employee of the Los Angeles Angels. We will not rest until we learn the truth about how Tyler came into possession of these narcotics, including who supplied them."
