SAN ANTONIO -

As Roger Hernandez lay dead alongside the curb in the 1200 block of Schley Street, Joshua Orcasitas called 911 while he fled the scene on the evening of July 11, 2012.

“My mom’s boyfriend, he attacked he and I killed him,” Orcasitas sobbed during a frantic call to the 911 operator. “I’m sorry I shot him.”

He told the operator that Hernandez, 43, had threatened to harm his mother, Delilah Orcasitas.

“I told him, 'No, you’re not. You’re not going do nothing to her,' and he said, 'Watch me, I’m going to be on the news tonight,'” the call continued.

Oracsitas, who was 19 at the time, is on trial for murder in Hernandez’ death.

His mother testified that earlier in the day of the shooting, she had thrown Hernandez, who was her live-in boyfriend, out of her home.

“I told him I was done, that it was over and that I didn’t want to be with him no more. “ she testified.

Orcasitas described Hernandez as a violent drunk and said only after she had allowed him to move in did she learn that he had previously been convicted on rape and assault charges.

If he is convicted of murder, Orcasitas is facing a maximum sentence of life in prison.
