A next-door neighbor to the house in Dixon where a married couple was found dead Saturday morning added new details to the case that police have classified as a murder-suicide.

Husband and wife Carlos Salinas, 45, and Kristy Adams, 43, both of Dixon, were found unresponsive inside the master bedroom at their residence in the 600 block of Devonshire Drive shortly before 9 a.m. Saturday. Dixon Fire Department personnel responded to a report of a “suspicious circumstance” and pronounced them dead at the scene.

Police later revealed Salinas stabbed Adams to death with a knife before stabbing and killing himself, sometime Friday night.

According to next-door neighbor, Don Harness, the couple was discovered in their bedroom by their 10-year-old son — the oldest of their two children — early Saturday morning.

The boy apparently left the home with his 7-year-old brother, the two still in their pajamas, and proceeded to walk over to a relative’s house located on Amesbury Drive, just one street away from their home, Harness said.

A relative of the home then went to the residence of Salinas and Adams, and after seeing the bodies, called 911.

Harness recalls seeing the fire trucks and police cars arriving at his neighbor’s home that morning, as well as a distraught woman running on the sidewalk toward the house while on her cell phone screaming, “They’re dead, they’re dead.”

Harness said he didn’t remember overhearing his former neighbors arguing, and that he was never led to suspect their marriage was abusive.

“There were no signs of disputes,” Harness said. “They appeared to be a good couple.”

Harness added that the tragedy was a “shock to the entire neighborhood.”

Dixon police said both Salinas and Adams were last seen around 9:30 p.m. at their home by visiting relatives, and that Salinas’ motive is still unknown.
