This was a deadly year in the Mid-Columbia.
Twelve deaths were classified as homicides in Benton and Franklin counties in 2013.
A third of the victims were younger than 18. The number included two teens who were killed in a high-speed crash, another teen who was shot execution-style in a remote area of Richland and a 9-month-old baby who was raped and killed, investigators said.
Of the known suspects, five are teenagers charged with murder or vehicular homicide.
Never miss a local story.
"This type of violence all in one year is unprecedented," Richland police Capt. Mike Cobb told the Herald this fall after the city's third homicide. "Two of them were domestic situations. It's just extremely unfortunate."
In all, four of the homicides involved domestic violence.
And in two other cases, police have yet to identify and arrest a suspect.
