The Utah County Attorney's office has filed second-degree murder charges against Georgia Clements, 52, in the bludgeoning death of her 17-year-old son.

Pleasant Grove police were called to the family home at 4:30 p.m. Monday to investigate what they believe was a murder/attempted suicide. Martin Clements was dead at the scene. An autopsy by the state medical examiner concluded that the boy died in the morning from multiple blows to the head. Investigators believe the weapon may have been a hammer confiscated from the house.The teenager also had several deep stab wounds, possibly from a kitchen knife found at the scene.

"There was no evidence of a struggle," Pleasant Grove Police Chief Michael Ferre said earlier this week. "We think the boy may have been asleep when he was struck."

Ferre said family members reported no arguments or bad feelings between the mother and son.

Clements suffered several deep stab wounds to her abdomen. She had also ingested diazinon, an insecticide used mainly to kill flies.

Clements was taken to American Fork Hospital where she underwent surgery. The knife reportedly missed all her vital organs. She remains in intensive care, and her condition Friday evening was listed as serious but stable.
