San Antonio, TX: Teen held in stabbing death

San Antonio police arrested a teen accused of fatally stabbing his mother's boyfriend during a disturbance at a South Side home Saturday night.
The 35-year-old victim, whose name has not yet been released, died around 11:15 p.m. at San Antonio Military Medical Center, according to the Bexar County medical examiner's office. He was stabbed in the chest in a home in the 100 block of Glenwood Court around 10 p.m. Saturday, police said.
An SAPD spokesman said the teen, 15, was in custody Sunday and faces a charge of murder. Because he is a juvenile, his name has not been released.
Neighbors said the teen's mother and her boyfriend, who moved into a single-story white rental home about seven months ago, were known to argue but weren't physically violent. On Saturday night, the woman returned home to find the man allegedly doing cocaine in the kitchen with a prostitute, SAPD Sgt. Jesse Garcia said at the scene.
She chased the suspected prostitute out of the house, Garcia said, and then got into an argument with the man.

The argument then escalated somewhat, police said, and items were thrown around the home. The couple knocked over a table and some chairs, police said.
While the couple argued, the teenager grabbed a four-inch knife, described by neighbors as a knife attached to brass knuckles. The man was reportedly leaving the house when he was stabbed in the chest; he collapsed on the front porch steps.
Delia Gonzales, 28, said the woman ran to her apartment for help, screaming hysterically that the man had been stabbed. She said she saw the teenager was pacing, still holding the knife, on the sidewalk in front of the home, where he waited until police arrived. He was detained and later taken into juvenile custody.
“We were so surprised,” Gonzales said. The teen and his mother's boyfriend were friends, she said. “They would walk around together, they barbecued together ... they were good together.”
The victim was Gonzales' friend, she said. Gonzales' boyfriend, Michael Postelle, 25, said he talked to the teenager after the stabbing while the boy's mother stayed by her dying boyfriend's side.

“We stayed because we didn't want her to get hurt,” Postelle said. “She's a good mom. I told him, if you stab your mom, I'm going to hurt you.”
Gonzales and Postelle said the teen was troubled and might have had anger management issues. He had run away from home before, they said, and had recently returned and enrolled in school.
Two other children, ages 7 and 10, were in the home at the time of the slaying and were placed in the care of relatives, said Mary Walker, a spokeswoman for Child Protective Services. Neighbors said the children were asleep during the incident.
Walker said her agency is investigating the family but was unaware if they had a history with CPS.
