SAN ANTONIO -

A man was shot and killed inside his West Side home Monday evening, San Antonio police said.

The Bexar County Medical Examiner's Office identified the victim as 41-year-old Bill Padilla.

Padilla's body was discovered just after 7 p.m. Monday night in the 200 block of Charben Drive.

Police believe the shooter may have followed the victim inside or was let in because there was no forced entry to any part of the home.

An SAPD sergeant said the victim could have known the shooter and it appeared it was more than an execution style assault.

A motive was unknown Monday evening and police were questioning family, friends and neighbors about the shooting.
