Olgin died at the scene, while Chapa is still in critical condition but has regained consciousness. The suspect is described as a "white male in his 20s with dark hair," and is estimated to be 5-foot-8 and weigh about 140 pounds.
Olgin and Chapa had been together since February and had stopped in the park before going to a movie when they were shot. The two were found in knee-high grass at Violet Andrews Park with no signs the shooting was a hate crime.
The couple's shooting has sparked vigils in New York, San Diego and El Paso. Chapa's family has also opened up a fundraising page for donations to help with her medical expenses.
