A 51-year-old man accused of killing his elderly parents on Saturday has been booked into jail on suspicion of first-degree felony aggravated murder.
Robert John Liddiard was arrested at about 8:30 p.m. Saturday, about three hours after Unified police found Robert and Diane Liddiard, ages 85 and 78, respectively, dead inside their Holladay home.
About 5:30 p.m. Saturday, police found Robert and Diane Liddiard at a home near 4700 S. Wander Lane after being called there for a welfare check, Lt. Brian Lohrke has said.
“There was evidence recovered from the other residence and on [the suspect’s] person linking him to the primary scene,” according to a jail probable cause statement obtained Monday by The Tribune.
