A mother used duct tape to suffocate her three little girls, then climbed into bed with them and took an overdose of prescription drugs, police said Tuesday.
Megan K. Hogg, 25, was treated at a hospital, then booked for investigation of homicide and taken for a psychiatric evaluation.
Ms. Hogg left two notes describing her actions, police said.
"In 29 years, I've seen a lot of evil. Nothing like this," said Lt. Steven Lowe.
Ms. Hogg's parents found the bodies of Antoinette Marden, 7; Angelique Roberts, 3; and Alexandra Hogg, 2, in bed next to their unconscious mother Monday morning. Ms. Hogg lived with her parents.
Ms. Hogg overdosed on several prescription drugs in what Lowe called "a suicide gesture. I don't think she intended to kill herself."
Friends and relatives said Ms. Hogg was an adoring and gentle mother who had not appeared depressed or unhappy.
