Houston residents have been warned about a “possible serial killer” on the loose after a rash of attacks in the last week. At a Monday night press conference, police identified the suspect as Jose Gilberto Rodriguez, a parolee who cut off his ankle monitor and is believed to have gone on a killing spree. Rodriguez is suspected of killing a 62-year-old homeowner in Harris County before stealing her car. He then allegedly committed a second and third murder at two mattress stores. Two other people were attacked but survived. Police say Rodriguez is armed and dangerous, and he may be going from door to door in residential areas pretending to be looking for someone. “The sooner we can get him into custody, the sooner we can all breathe better,” Houston Police Chief Art Acevedo said Monday.
