According to court documents:

Midnight: Oscar Rosales picked up a white Toyota Avalon from the home he shared with his common-law wife of 17 years, Reina Azucna Pereira Marquez. He left his white Dodge Ram pickup in their driveway.

Rosales told his wife that he was going hunting or shooting with friends and took two long guns with him that he had kept in a safe. He was the only person with a key to that safe, Marquez told investigators.
