The man who escaped from a federal prison in Florence after being convicted for sending spam e-mail killed his wife and one of their children before killing himself in an apparent murder-suicide on Thursday.

Eddie Davidson, 35, was serving a 21-month sentence for illegally sending spam over the Internet and escaped from a minimum security prison in Florence on July 20.

At around 11:15 a.m. Thursday, the Arapahoe County Sheriff’s Department received a report of shots fired in the area of East Arkansas Place, at Davidson’s former home.

Around the same time, according to the sheriff’s department, a female teenager arrived at a neighbor’s house with a gunshot wound to the neck. She was taken to a hospital with serious injuries.

When sheriff’s deputies arrived at the house, located in the 43000 block of East Arkansas Place, they found a dead woman and a dead man lying next to a silver Toyota Sequoia in the driveway. They also found a dead 3-year-old girl inside the SUV.

The U.S. Attorney’s office says the man, Davidson, died from a self-inflicted gunshot wound. The U.S. Attorney’s office says Davidson’s wife, Amy Hill, and their 3-year-old daughter were the other two who were killed and they both died from gunshot wounds.

Their infant son, about 7 to 8 months old, was found unharmed inside the back of the SUV still in a car seat. He was taken to a local hospital where he was treated for dehydration.

All of the deceased suffered from gunshot wounds, as did the teenage girl.
