SAN ANTONIO -- A home invasion on the city's east side Saturday ended in gunfire as the homeowner fatally shot the intruder, police said.

According to police, the intruder broke in through a window, but he didn't make it far.

The invasion and shooting happened Saturday at about 10 a.m. in the 1400 block of South Palmetto.

Police said the intruder, a man in his early 30s, slipped in through the back window of the house.

They said the homeowner had been sleeping inside but must have heard the intruder breaking in.

"(The homeowner) woke up, grabbed a rifle, confronted the person (and) shot him inside the house," San Antonio Sgt. Steven Peterson said. "(It) looks like the person was able to get back out the window and collapsed in the back yard and died."

Police said the intruder died at the scene of an apparent gunshot wound to the upper torso before paramedics could arrive.

Officers took the homeowner to the police station so he could give a detailed statement.

Peterson said the San Antonio Police Department's Homicide Unit is investigating the shooting.

No charges have been filed against the homeowner, police said, and officers at the home said based on the information they had, it looked like the homeowner acted in self-defense.
