The teenager accused of stabbing a 54-year-old man on Saturday had been performing oral sex on the victim moments before he attacked the man, according to a preliminary police report.

Job Israel Davila-Rangel, 17, faces a charge of aggravated assault with a deadly weapon. He was booked into the Bexar County Jail on a $75,000 bond.

According to the police report, Davila-Rangel told officers he was performing oral sex on the victim around 2:30 a.m. at a home in the 300 block of West Mally Boulevard when he "decided what he was doing was not right."

"[Davila-Rangel] said something came over him, and he began to stab [the victim] repeatedly," the report says. Police later told reporters that Davila-Rangel cut the victim across the neck from ear to ear.

Police came to the home and found both Davila-Rangel and the man, who told police Davila-Rangel "became wild" and stabbed him, the report says. Davila-Rangel then allegedly admitted to the attack.

Paramedics took the victim to Brooke Army Medical Center in stable condition, and Davila-Rangel was booked into jail.

According to police, the stabbing victim will not face charges for having sex with a 17-year-old because someone who is 17 years of age is considered an adult.
