A suspect is in custody, he has been identified as Gilbert Manriquez, according to Fox San Antonio.
The Kerr County Sheriff's office says 52-year-old Sherry Francis had just pulled in to work Wednesday morning around 5:00 am when deputies say Manriquez came up to her car.
"He was according to his own omission, in a drug craze, and thought he walked up to a house, the lady told him to leave and he ended up attacking her, right when she drove up and got out of her vehicle," said Kerr County Sheriff Rusty Hierholzer.
Investigators say Manriquez has no apparent association with Francis or the radio station and they are calling this a random act of violence. During questioning, Manriquez did confess to killing Francis.
"She was a ball of energy, on air and off air, she really got it, she really loved her job and she fit in so well, "said Owner of Ranch Radio, Mark Grubbs.
Francis had only worked here for four weeks.
The station posted a statement on their website:
All of us at the Ranch are shocked and heartbroken at this random act of violence. Our thoughts and prayers are with her family, friends and loved ones. Respecting their privacy, we will not comment on any details of this tragedy.
