According to investigators, Tomas Santoyo Rodriguez, 41, turned himself in around 8:30am and told police where to find her body.
Officials said the woman's body was in a car in the Walgreens parking lot in the 12600 block of South Gessner. The victim, Emelia Oregon-Cruz, 27, of Fresno, had suffered multiple gunshot wounds. She was pronounced dead at the scene.
Police say that on Saturday, Rodriguez apparently found out that Oregon-Cruz, his common-law wife, was going to meet her boyfriend at the Walgreens. Rodriguez reportedly drove there and saw her vehicle parked. He's then said to have parked his van and waited for her to return.
At about 1am Sunday, police say Oregon-Cruz returned to her vehicle. As she was approaching her car, Rodriguez allegedly forced Oregon-Cruz into his van at gunpoint and shot her. He then left her in his van, took her car, and fled the scene.
Rodriguez turned himself in to the Pearland Police Department, which contacted the Houston Police Department to take custody of Rodriguez.
The store did not open until 9am. There did not appear to be any witnesses.
Rodriguez has been charged with murder.
