Oscar Velazquez had been dating Regina for roughly 3 weeks before the murder occurred. Regina called him to her apartment, where she, her sister, and their friend Veronica Garcia were waiting. Veronica had provided Regina with a .38 caliber semi-automatic pistol to rob her boyfriend at gunpoint.
However, we can assume that the plan went wrong at some point since instead of robbing Regina’s boyfriend, Margaret shot him in the back of the head.
They looted whatever cash he had and then used his car to transport the body to a vacant parking lot where they consequently set it to fire. It is reported that they also tried to sell his vehicle, a Camaro Z28, but failed to do so and were forced to set it on fire too.
A passerby immediately called 911 when he saw a body in the fire. The police’s suspicions immediately were focused on the sisters, and they were further ironed when the sisters gave confused and inconsistent testimonies. Realizing that the game was up, they fled, and thus the cat and mouse chase began.
