The incident happened around 10 p.m. in Bob White, according to a release from the sheriff’s office. Police say the homeowners were alerted by a neighbor that someone was possibly in their back yard. The man and his wife, whose names have not been released, went to investigate. They encountered Jack “Anthony” Webb, 40, of Wharton, as he came out of the family’s outbuilding. Wharton, who police say was armed with a knife, was shot once and pronounced dead at the scene by emergency service personnel.
