Diamond Amie Alvarez, 16, of Houston, Texas, was shot to death on January 11, 2022. Described by family as kind, funny, and beautiful, she was an honor student who liked dancing, taking pictures and helping others. Her family says she left to walk the dog, Peanut, and did not return; they heard gunshots soon after and the dog came back covered in Diamond’s blood.

Investigators say the shooter was Diamond’s ex-boyfriend, 17-year-old Frank DeLeon Jr., who allegedly shot her multiple times in a neighborhood park after she discovered he was cheating. DeLeon was arrested and charged in connection with the killing; later court proceedings resulted in a plea and a 45-year prison sentence. Family members described a tumultuous sentencing hearing and said they endured threats and harassment while seeking justice.

What can anyone who knew Diamond, her movements that night, or the park area add to help complete the timeline?
