All seven victims have a "familial relationship" to the suspect, identified as 35-year-old Bradley William Stone, said prosecutors in Montgomery County, Pennsylvania yesterday.
Police said Stone -- possibly wearing military fatigues -- should be considered "armed and dangerous."
No possible motive was given for the shootings.
One of the dead is believed to be a woman who was killed in her house in the middle of the night. Her neighbour told local media the suspect then left the home with her children.
The shootings took place at three different locations in suburban Philadelphia -- Souderton, Lansdale and Lower Salford.
Police were searching in a fourth location, the town of Pennsburg, where Stone is a resident, prosecutors said.
Reinforcements were rushed in to aid the manhunt for Stone, who uses a cane or a walker, according to police.
