Cleveland Serial Killer's Mother Murdered by Her Own Grandson!

67-year-old Diane Madison was found dead in her home this morning after two young children roused neighbors shortly after midnight.

Three children, ages 10 through 12-years-old, had also been stabbed inside of the home on Chickasaw Avenue in Cleveland. Two of those children were able to run to a neighbors house for help. The children identified 18-year-old Jaylen Latrell Plummer, who was the sibling to two of the victims and cousin to another, as their attacker.

Sources say that Plummer entered the bedrooms of his grandmother and the children and stabbed them all while they were sleeping. After the attack he got into the shower where police found him covered in blood.

Plummer was taken to the hospital for treatment of wounds to his hands. The children were taken to Rainbow Babies and Children's Hospital and Diane Madison was pronounced dead at the scene.

According to Cleveland.com:

"A 10-year-old girl and her 12-year-old cousin required surgery, court records say. All three children are still hospitalized, according to court records."

Mrs. Madison is the mother of Cleveland serial killer Michael Madison. "Michael Madison - who registered as a sex offender in 2002 when he was sentenced to four years in prison for attempted rape - was apprehended at his mother's home in East Cleveland July 2013 after a two-hour standoff.

His arrest came after the decomposing bodies of Angela Deskins, 38, Shetisha Sheeley, 28, and 18-year-old Shirellda Terry were found wrapped in garbage bags secured with tape near his apartment.

Madison said at the time he admired local serial killer Anthony Sowell, known as the Cleveland Strangler, who remains on death row in Ohio for the murders of 11 women.

During his trial, Madison's defense lawyers told the jury his mother, Diane, abused him as a child."

One of the children hurt by Plummer is said to be the child of Michael Madison.

UPDATE:

Plummer was in court on Monday with his hands bandaged. He is facing murder charges and is being held on $2 million bond.
