On October 15, 2022, 18-year-old Andres Arigullin II was found dead on the living room floor of an apartment on Tampa Street in Edinburg, Texas. Officers arrived to find him surrounded by blood; initial reports said he had shot himself but later investigative steps changed that account.

Andres’ 21-year-old sister, Carmen Del Crystal Arigullin, was taken in for questioning after officers noted blood on her feet. She first told police their brother had shot himself, then admitted she had pulled the trigger. Police say she had been playing with a handgun, pointed it at Andres’ face and fired. No other witnesses were identified and authorities charged Carmen with murder; she was arraigned on a $1 million bond and was to be transferred to the county detention center to face formal charges.

What can people who knew Andres or were in that neighborhood on October 15 tell investigators?
