Marcia Maglisco

A Connecticut grandmother who hanged herself days after claiming to have drowned her grandson in a bathtub told 911 dispatchers that she was psychotic and wanted the police to shoot her, according to a transcript of the call. Aidan Blake Halter, 2, drowned in a bathtub in his home in Foxbridge, Conn., Friday, October 5, 2007, while his grandmother, 62-year-old Marcia Maglisco, was babysitting. Maglisco said during the call that the toddler slipped and hit his head during the bath, and that instead of helping him, she left him under the water.

After repeatedly telling the dispatcher that her grandson was "deceased" and could not be saved, Maglisco described the events surrounding the boy's death. "I'm psychotic...he was in the tub, he slipped, he banged his head and I just left him," she said. "I want the police to shoot me, if they could."

Janice Robbins

An Arkansas nurse who adopted her granddaughter* after her son's death in Iraq stabbed the 7-year-old girl in the chest and then set fire to their home in an apparent murder-suicide on January 9, 2012. Janice Robbins, 63, left a suicide note in her pickup truck before killing her granddaughter, Abby Robbins, and herself on Saturday, Faulkner County sheriff's spokesman Maj. Andy Shock said. In the note, she wrote that she didn't want to leave the girl behind.

Officials said there were no indications Robbins was in financial trouble. However, she had dealt with depression. Authorities found a gas can next to each of the bodies inside the lakeside home, which was engulfed in flames by the time firefighters arrived early Saturday morning.

* It should be noted this case is dissimilar from others memorialized here since Robbins had become the child's mother.

Lisa Antoinette Humphrey

Lisa Antoinette Humphrey, 47, was charged with first-degree reckless homicide but pleaded no contest in June 2012 to second-degree reckless homicide. She was sentenced to 14 years in prison, followed by seven years of extended supervision.

Royality Sanders, 10 months old, was found dead April 28, 2011, on the mattress he had shared the night before with Humphrey and his 2-year-old sister. Humphrey told police she was baby-sitting the children in an apartment she shared with their mother in the 5100 block of N. 47th St., according to the criminal complaint. Humphrey said she fed her grandson from a yellow bottle before putting him to sleep on the mattress.

The Milwaukee County medical examiner's office tested the contents of the bottle and found that it contained morphine. A blood screen of Royality tested positive for both opiates and oxycodone.

Sandra Layne

Sandra Layne is a former schoolteacher, mother of five, grandmother of nine and at 74 years of age, an accused killer.  It was May 18, 2012, at 5:27 in the evening, when officers were called to Layne's upscale condo on Brookview Lane after a neighbor heard gunshots.

Officers arrived to the sound of more gunfire from inside the home. At the same time, Layne's grandson Jonathan Hoffman was on the phone with 911. It was determined ten shots were fired from Layne's gun, a Glock she recently purchased.  Half of the bullets hit Hoffman at close range. The 17-year-old was shot three times in the chest, once in the arm and once in the stomach.

Layne's attorney says Hoffman's drug use set off the argument that led to the deadly shooting. Dr. Reuben Ortiz Reyes testified Hoffman tested positive for K2 in his urine, but not his bloodstream, so he wasn't under the influence of drugs at the time.

"He tested positive for spice.  It was a violation with his probation.  He was concerned about going to jail and he wanted to do certain things, and that's when the argument erupted," said Jerome Sabbota, Layne's attorney.  "She was fearful.  She killed a person that she loved, that she tried to save.  There are no winners.  No matter what we do to her, it doesn't really matter.  Watch her.  She's in her own hell."

Sandra Layne is currently awaiting trial.
