WEST JORDAN, Utah (AP) — Members of a Utah community gathered at a weekend vigil to mourn the loss of a couple police believe were killed by an intruder. The Saturday night vigil was held to commemorate 30-year-old Katherine Butterfield and 31-year-old Tony Butterfield. Police say the Butterfields were killed early Saturday in their home in West Jordan.  Police say they were found shot dead in the backyard and inside the home. The suspect appeared to have rummaged through the home, but police were not sure what may have been taken. The couple’s three children, all under 4 years old, were unharmed.
