Two men and a woman were arrested Friday in connection to a slaying in December of a man south of Tucson, authorities said.

Jessica Rodriguez, 26, and Aaron Heath, 35, were arrested in Tucson and Rodriguez's brother, Joel Rodriguez, 28, was arrested in Phoenix, said Deputy Cody Gress, a Pima County Sheriff's Department spokesman.

Heath was booked into the Pima County jail on suspicion of first-degree murder, and Jessica Rodriguez was booked on suspicion of conspiracy to commit first-degree murder, said Gress. Joel Rodriguez was booked into the Maricopa County jail on suspicion of first-degree murder, Gress said.

Detectives served multiple search warrants in Tucson and Phoenix during the investigation of the shooting death of Richard Jensen, 36, on Dec. 11 in the 1000 block of East Fenley Drive.

The neighborhood is west of South Nogales Highway and south of East Old Vail Road.

Deputies responded to the shooting scene shortly after 2 p.m. and found Jensen with multiple gunshot wounds. Jensen was treated at the scene by deputies until paramedics arrived and transported him to a hospital where he was pronounced dead.

Homicide detectives learned from witnesses that a vehicle fled the scene and it was occupied by two men.

Gress said the investigation is continuing.
