Two people were arrested Tuesday night in connection with a Sunday shooting on the southwest side that left a man dead, authorities said.

20-year-old Ramon Duran-Avila and his cousin, 19-year-old Lizardo Duran-Rojas were taken into custody shortly after 10 p.m., and charged with first degree murder and weapons misconduct, said Pima County Sheriff's Department spokesman, Deputy Cody Gress.

Shortly after 8:30 p.m. Sunday, deputies responded to calls of a shooting at a home in the 4300 block of West Valencia Road, and found 45-year-old John Murray dead at the scene.

Sheriff's department SWAT officers, detectives and members of the Fugitive Investigative Strike Team served a search warrant Tuesday night at an address in the 3500 block of South Gold Flower Avenue, in the area of West Bopp and South San Joaquin Road, finding Duran-Avila and Duran-Rojas inside the residence.

The Sheriff's department said Sunday that a second shooting call was related to the incident that left Murray dead. About 30 minutes after responding to Murray's address, deputies arrived at a house in the 5000 block of West Tillery Street, and found a man with gunshot wounds. He was transported to the hospital and was listed in serious condition. No charges have been filed against the suspects in association with this crime.

The investigation is still ongoing.
