Charles County Sheriff's deputies responded to reports of a shooting where they discovered the bodies of suspected shooter Andre Sales, 28, his ex-girlfriend Sara Mann, 21, her brother, Kai Mann, 18, their mother, Sommaly Mann, 48, and another male Jovon Watson, 23.

Officials received the concerning report at 4pm after the homeowner, identified as Darin Mann, said he returned from work to discover the dreadful scene, his brother Robin told The Washington Post.

A preliminary investigation revealed that Sales, who lived at a separate residence, entered the home before opening fire, officials believe.

He then fatally shot himself with a gun that was recovered at the scene.

Investigators are still working to determine a motive for this tragic incident, but the sheriff's office is investigating what is believed to be an ongoing domestic dispute.

Robin Mann said that Sales was the father of Sara Mann's two young children, and police confirmed that he lived at the residence for a time.

Court records show that an unidentified person filed a restraining order against Sales in April 2021 that prevented him from going to the individual's place of work or home, the Post revealed.

Robin Mann said his niece and nephew were "good kids," and had difficulty describing the horror event.

"What can you say?" he said.

"They were full of life," he added.

Sara Mann's two young children were initially unaccounted for during the horror event, but were found safe and unharmed at another location.

Investigators and forensic personnel are processing evidence and interviewing family and friends to determine a motive, cops said.

A medical examiner will determine the cause of death.

The sheriff's office initially said that all five victims suffered gunshot wounds, but later added that some also had stab wounds.

Sales had misdemeanor convictions for assault and theft but no felonies were recorded, according to the Post.

Authorities are deeming this an isolated incident.

Footage from local stations after the crime shows police cars and officers flooding what appears to be a normally quiet neighborhood.

"This is obviously something that has affected the whole community," said Charles County Sheriff's Office spokesperson Diane Richardson.

"There was a lot of people in the immediate neighborhood who came together to mourn.

"It was tragic for the neighborhood, the family, and even the officers who responded.

"Our hearts are heavy."
