Johnson told police that he decided about 4 a.m. on Monday 12th March that he would kill Jovanni, Dane and Dane’s mother before they woke up.

Johnson first went to a loft area where Jovanni was sleeping and fatally stabbed him and cut his throat.

Around 5:45a.m., Simon - awakened by commotion and the sounds of Jovanni moaning - went upstairs to check on her sons and their two friends.

Johnson attacked her next, stabbing her so many times that she fell down the stairs; Johnson also stabbed Dane 32 times, as he tried to protect his mother.

When officers responded, they found Simon and Dane severely injured.

Jovanni was pronounced dead at the scene; it was the morning of his 13th birthday.
