Iowa Family Mass Shooting

Six people were killed in a series of shootings in Muscatine, Iowa, believed to have been carried out by a relative who then took his own life.

The lone survivor of the family massacre was the 22-year-old son, who escaped death as his father murdered six family members in a horror rampage.

Four of the victims were students and employees at a local school district.

Authorities are investigating the incident, which appears to stem from a domestic dispute.
