Police have arrested four people in connection with two separate deadly shootings in Pueblo.
Authorities say 65-year-old Richard Dean Whitlock died from multiple gunshots at his stepson's home. The stepson, 46-year-old Bradley David Chandler, was arrested on suspicion of first-degree murder.
Chandler's mother, 65-year-old Rochelle Rae Chandler, told investigators that Whitlock had been unfaithful to her and was going to leave town with another woman.
An affidavit shows she told investigators that her son always defended her.
Meantime, police say 26-year-old Amanda Ann Sanchez died from a single gunshot wound to the chest after she went to pick up her mother from a party.
At least five shots were fired as her mother, Lillian Sanchez, argued with three people.
Police arrested 24-year-old Alvin Rasha Lark and 21-year-old Mario Eugene Bonetta on suspicion of first-degree murder.
Twenty-year-old Liani Sandoval was arrested on suspicion of complicity to first-degree murder.
Lark and Bonetta are being held on $500,000 bond.
Sandoval's bond is set at $250,000.
