LANCASTER – A Lancaster man was arrested after a fatal shooting Monday night at the A-Plus store at 111 W. Orange Street. 21-year-old Carlos Almanzar-Torres is charged with criminal homicide and recklessly endangering another person. Police say Torres and 19-year-old Damian Santiago of Lancaster were inside the store when Torres pulled an handgun and shot Santiago. Torres fled and then came to the Lancaster City Police Station approximately an hour after the incident to turn himself in to police. Santiago was taken to a hospital, but died from his injuries. Investigators learned that Torres and Santiago were known to each other and this was not a random act of violence. Torres has been taken to the Lancaster County Prison for arraignment. The investigation continues.
