The girlfriend of an off-duty police officer has been charged with shooting him to death inside his home after she originally contended it happened accidentally when she removed a gun from their dog 's mouth , authorities said . Tyaina Finch was charged with murder , aggravated assault and possessing instruments of crime in the death of Mark Hudson in Darby Township , near Philadelphia , on Saturday . Hudson had worked part-time for the Darby Borough Police Department for four years . The dog did it : Slain Darby Borough Patrolman Mark Hudson ’ s girlfriend , Tyaina Finch , initially told investigators he was mortally wounded as she tried to retrieve his duty weapon from their yellow Labrador retriever ’ s mouth . Tribute : Funeral arrangements are set and a vigil was also held Wednesday night for the Darby Borough police officer who was killed allegedly at the hands of his girlfriend . District Attorney Jack Whelan said Finch 's statements to police had been 'inconsistent . ' He described the couple 's relationship as 'tumultuous ' and said officers had been called to the home before for domestic disturbances . 'We believe she acted on this particular day with specific intent to kill ( Hudson ) , ' he said . Finch , who was held without bail , could n't be reached for comment by telephone on Tuesday . The county public defender 's office could n't be reached for comment on her behalf . The story : While Finch told investigators she does not recall pulling the trigger in their Darby Township row home , the affidavit of probable cause indicates she remembers dropping the firearm after Hudson ’ s body jerked back and his shoulders hit the wall in a bedroom , where he was found lying in a corner , unresponsive . Authorities allege in a criminal complaint that Finch , who 's from Glenolden , at first said the shooting occurred accidentally : She saw their dog with a gun on the floor and took the gun from the dog 's mouth , and as she turned toward Hudson the gun went off . The following day , police allege , she told officers she fired the gun in self-defense after Hudson attacked her . Authorities said a caller identifying herself as Finch on the day of the shooting told an ambulance dispatcher 'we were playing and I did n't know that his gun was right there and it went off . ' Finch told a police officer arriving at the scene 'it was an accident , ' the criminal complaint says . Finch was arrested Monday on threat and assault charges stemming from a dispute last summer during which authorities allege she threatened Hudson with a knife . History of arguments : Last summer , the two were in the middle of a break-up and Hudson had told her to leave his home . During the argument , Finch allegedly grabbed an 8-inch kitchen knife while screaming at him . Hudson hid in an upstairs bedroom , locked the door and called police , investigators said .
