Correction: The killing occurred in 2009. An earlier version of this story had an incorrect date.
Myrahn Johnson awoke to a shouting man's voice in the living room of his mother's house.
The 12-year-old then saw a shadow at the window, following by the sound of breaking glass.
By the time he got out of bed and walked out of his bedroom, Myrahn said in court Tuesday, he saw his mother running to the door and her ex-boyfriend running after her.
Yusef Samad Sr. grabbed Mechelle Reed and pulled her to the floor, Myrahn said. Samad then punched her in the neck with a tire tool, Myrahn testified at a preliminary hearing.
Reed died of multiple stab wounds to her neck and chest, according to an autopsy. Sedgwick County District Judge J. Patrick Walters ordered Samad to stand trial on charges of first-degree murder, aggravated burglary and endangering a child.
Samad pleaded not guilty. His trial is tentatively set for Aug. 1.
Reed had filed several requests for protection from abuse from Samad beginning two years before her death on July 12, 2009.
It has taken two years for the case to come for a preliminary hearing because Samad underwent treatment for mental competency, court records show. He is diagnosed with bipolar disorder and schizophrenia, according to court records and his family.
Myrahn said he had gone to bed early when he heard the man screaming in the other room.
Samad's lawyer, Brad Sylvester, asked about episodes of anger Samad had displayed before. Myrahn said he had heard the tone of voice Samad was using toward his mother before. He had seen a previous argument earlier that same day.
After the window broke, Myrahn said Samad wrestled Reed to the floor, grabbing her in a bear hug.
Myrahn, now 14, also testified he tried to help his mom.
"I picked up a radio and threw it at him," Myrahn said.
It hit Samad in the neck. Myrahn said he threw a DVD player but missed.
Then Myrahn went to the kitchen.
"I was going to get a knife," the youth told prosecutor Marc Bennett.
"Don't do it," Myrahn remembered his mom telling him. She told him to get out of the house.
Myrahn said he already had seen Samad punch his mother in the neck with a tool. Police would later learn it was a tire awl, which is used to repair punctured tires.
The youth said he ran out the back door. He saw a man standing by a truck outside. Rodney Wiggins, 23, later testified he worked at an auto repair shop where he had met Samad.
Myrahn said he saw his mother come out of the house, bleeding; Samad ran after her.
Wiggins was visibly upset seeing the bleeding woman, Myrahn testified.
"What did you do?" Myrahn said Wiggins yelled.
"I'll fix it," Myrahn heard Samad answer.
After Wiggins and Samad drove off, Myrahn said Reed went to a neighbor's house.
A neighbor called 911.
"Go," Myrahn remembered his mom telling him, motioning toward the house.
Myrahn said within minutes, paramedics arrived at the house in the 2700 block of North Estelle. Police followed. They began asking Myrahn what happened.
The rest of the night was a blur for the 12-year-old, who said he didn't know his mother was hurt so badly that she would die.
