Yosselyn Alfaro was 21 when she was killed in a mass shooting at an apartment in the Copperfield area of Houston on November 20, 2013. She was celebrating her 21st birthday when the attack left her and two teenagers, 17-year-old Veronica Hernandez and 17-year-old Daniel Munoz, dead; two other people in the apartment were wounded and survived.

Investigators said Sanchez had threatened people at the Peppermill Place Apartments and had been using hallucinogenic drugs in the days before the killings. A surviving witness identified Sanchez, and he was arrested a few days after the shooting and charged with capital murder.

Does anyone have more information about the victims or the community impact around Copperfield at that time?
