Rachael Koloroutis, 18, was one of four young people shot to death on July 18, 2003, in a home in the Clear Lake neighborhood of Houston. A recent Clear Lake High School graduate who had jobs at The UPS Store, Randalls and Denny’s, she co-led a youth drama ministry and worked as a counselor at summer camps. Rachael was found crawling on the floor with a phone near her hand, suggesting she tried to dial 911 before she died; the victims had been shot multiple times at point-blank range.

The investigation produced major leads three years later after an anonymous tip identified two people connected to the killings: Christine Paolilla, a former classmate of Rachael and one of the other victims, and her boyfriend Christopher Snider. Paolilla was subsequently arrested and tried; Snider died by suicide after learning police were closing in. The families, including Rachael’s parents George and Ann Koloroutis, raised reward money and distributed composite sketches during the long search for answers.
