The Washington County Sheriff's Office says three people have been found dead of apparent gunshot wounds in a single-family home near Hagerstown.
A spokeswoman says investigators are not looking for any suspects.
She says deputies were called at about 4:20 p.m. Thursday to the home on Dawn Drive in the unincorporated community of Halfway, southwest of Hagerstown.
The Sheriff's Office says the home is in a residential area near two elementary schools.
Police have identified the deceased as William Frank Smith, Jr, 54, Kimberly Anne Smith, 47, and Christopher Michael Wachter, 23.
All three individuals listed 17511 Dawn Drive as their residence.
In the initial investigation, officers believe Smith, Jr. killed Kimberly and Wachter before he suffered a self-inflicted gunshot to the chest.
Police say Wachter suffered multiple stab wounds and Kimberly suffered multiple stab wounds and a single gunshot to her chest.
Officers wrapped up their investigation around 9:30 p.m.
The bodies have been taken to the Baltimore Medical Examiner's Office for an autopsy.
