Terry Rasmussen was born in Colorado on Dec. 23, 1943. He attended high school in Arizona but dropped out to join the Navy in 1961.

Rasmussen was trained as an electrician and served for six years at bases around the West Coast and Okinawa. He married in Hawaii in 1968 and a year later, moved to Phoenix, Arizona, where the couple would go on to have four children. In 1975, he and his wife separated and it's believed that in 1975 or 1976, his family saw him for the last time.

Before Rasmussen died in a California state prison of natural causes in 2010 while serving time for the murder of his girlfriend, authorities in California and New Hampshire had yet to identify Rasmussen as responsible for killing at least four more people.

After his death, he was cremated and his ashes were thrown into the sea. He is suspected in the slayings of more victims.
