Horror as 'father and his three young children' - two girls and a boy - are found shot dead in a car in 'murder suicide' in Georgia

A man and three children have been found shot to death inside a car at a Georgia park in a suspected murder-suicide. 

The victims were found by a patrol officer at Lucky Shoals Park in Gwinnett County, which is part of the greater Atlanta metropolitan area, around 1am Wednesday.

The adult man, who was sitting in the front seat of the vehicle, appears to be the 'parent of the three children', officers at the scene told WXIA-TV.

Police have not identified the victims, but confirmed to DailyMail.com that the victims included two girls and a boy who appear to be elementary and middle school aged.

Officers are investigating the case as a murder-suicide, but say final determination will be made by the Medical Examiner's Office.

A Gwinnett County police officer was carrying out a routine check at Lucky Shoals Park on Britt Road early Wednesday morning when he 'stumbled upon' a 'suspicious vehicle' parked along the pedestrian trail.

The officer called out to the occupants of the vehicle but got no response. 

He then approached the four-door car and found the bodies of an adult man and three children dead inside. 

Detectives from the department's Homicide Unit said it is unclear when exactly the incident occurred.

They did not reveal many details about how the victims died, but confirmed their injuries included gunshot wounds.

'It appears the adult is the parent of the three children,' Sgt. Michele Pihera told WSB-TV, adding that the children 'appear to be two girls and one boy'.

Police are waiting to identify the victims until their family has been notified.

Sgt.

The entrance to the park is closed while officers carry out their investigation. 

The vehicle and victims' bodies will be removed from the scene.
