Relatives got a hint something was amiss with a Utah family killed in a murder-suicide when the couple and two young children failed to show up for a planned Father's Day visit.
Police say 29-year-old Russell Smith shot and killed his wife and two young children before turning the gun on himself Sunday at their home in Roy, about 30 miles north of Salt Lake City.
A relative discovered Smith's body, along with those of his wife, 26-year-old Shawna Smith, and their children, 6-year-old Tylee and 2-year-old Blake, that night.
Shawna Smith's mother, Sheila Pruitt of Tacoma, Washington, said Monday the family missed a planned Sunday visit to Russell Smith's family, but there were no signs violence before the deaths.
Pruitt says her daughter was a loving, dedicated mother.
Russell Smith's motive is under investigation.
