A man suspected in the murder of an 81-year-old woman and the attempted murder of two other women may have gone by a different name while working as a health care provider in North Texas.
Billy Chemirmir may have also gone by the name Benjamin Koitaba, Plano police said on Tuesday. Investigators believe people recognize him but know him as that name.
People with tips are asked to call police at 972-941-5785.
Detectives are going through hundreds of death cases to see if Chemirmir may be a suspect in more murders.
