A Maine man's killing of a woman and their son has underscored Maine's long-standing problem of domestic violence, which is linked to about half of homicides.

According to the Associated Press Attorney General Janet Mills said that last year, seven out of 16 homicide victims lost their lives following domestic violence.

Police say 51-year-old Carroll Tuttle Jr., of Madison, killed 52-year-old Lori Hayden, and their son, 25-year-old Dustin Tuttle, at their home. He then killed a neighbor, 57-year-old Michael Spaulding, at his home a short distance away.

Spaulding's son, also named Michael, told the Morning Sentinel that Spaulding was helping Hayden move away from Carroll.

A neighbor says Carroll had a temper and was jealous.

The shootings came to an end when Carroll was killed by police according to the Associated Press.
