Pennsylvania shootings: Six people killed in three locations in Montgomery County

Six people have been killed and three wounded in three locations in Montgomery County, Pennsylvania, officials say.

Montgomery County police are seeking the suspected gunman, who they named as 35-year-old Bradley William Stone.

They say he may be armed and dangerous, telling residents to remain indoors.

The victims are all said to have a familial relationship to Bradley William Stone, who has been described as having red hair and wearing military fatigues.

He also reportedly uses a cane or a walking stick.

The shootings in Harleysville, Lansdale and Souderton began at about 04:00 local time, according to local media reports.

One of the victims is believed to be a woman who was killed in her house.

Neighbors said they saw the suspect leave the house with two children, amid reports that the shooting may have been triggered by a custody dispute.

The children were reported to have been found safe a short distance away.

Police officers later surrounded a home in Pennsburg, where the suspect is a resident.

Shelter in place orders were issued for local schools.
