An autopsy says a New Mexico sheriff's deputy who authorities say a fellow deputy killed in a hotel was shot multiple times in the back and had other injuries that appeared related to a fight.

The report released Thursday says Santa Fe County sheriff's Deputy Jeremy Martin says suffered four to five gunshot wounds and bruises and scrapes on his body, including to his face and hands.

Authorities say former Deputy Tai Chan fatally shot Martin at a hotel in the southern New Mexico city of Las Cruces in October after they drank at a nightspot and got into a heated argument.

Police said the two deputies were staying at the hotel after dropping off a prisoner in Arizona.

Chan has pleaded not guilty to first-degree murder.
