Police have laid charges against a man and woman in connection with a homicide in Halifax’s south end.

Investigators say a 51-year-old man has been charged with second-degree murder and a 29-year-old woman has been charged with robbery and being an accessory after the fact to murder.

The Halifax pair was arrested Tuesday evening at two separate locations in the south end.

The arrests come after a man’s body was found inside a rooming house in the 5200 block of South Street Sunday evening. Officers responded to the residence before 11 p.m.

The victim has been identified as 65-year-old David William Rose.

Sources tell CTV News a man who lives in the shared unit found Rose in a common kitchen area with a plastic bag over his head.

Police say an autopsy has been conducted and Rose’s death has been ruled a homicide, but the cause of death will not be released.

Rose was originally from Newfoundland but had been living in the south end for several years.

Stephen Gates says he has been struggling to come to terms with his friend’s death.

“I can’t keep Dave off my mind,” says Gates. “Hopefully we find out what happened and people are held accountable.”

Rose was a retired widower who suffered from diabetes. He walked with a cane and was deaf in one ear.

Friend Jenny Fisher says she remembers Rose as a kind man who liked to laugh and cook for his neighbours.

“This is a senseless violent crime that is done by a sick individual and no one wants those kinds of people hanging around the public,” says Fisher.

Friends say he went to a local church regularly for meals, although he went more for the company than for the food. The daily church meal service is holding a memorial for him Friday morning.

“We are all really shocked and we’re going to miss him and we need more people like him around,” says Gates.

Police haven’t released a possible motive for the murder or say whether anything was taken from the home, but they don’t believe it was a random incident.

Sources say Rose’s death was likely drug-related.

Police say both are scheduled to appear in Halifax Provincial Court Thursday.
