Man Who Stabbed His Mother & Siblings in Atlanta Suburb Has Long History of Violence…

Psycho ain’t the word for this dude! Eugene Quatron McCoy, 21, was arrested and charged with the gruesome murder and aggravated assault of his mother and siblings in a suburb of Atlanta.

One of the sisters managed to escape the attack and ran to a nearby home to call police. She is the only survivor of the vicious assault.

It was recently revealed that McCoy’s mother actually had a restraining order in place against him, but it failed to protect the Lithonia mother and two of her children, who were allegedly killed by her son.

Details + McCoy’s extensive mugshot collection below:

The mother and two of her children were stabbed to death and her teenage daughter was critically wounded in a Sunday night knife attack allegedly by her oldest child, 21-year-old Eugene Quatron McCoy.

McCoy was arrested shortly after police were called around 8:45 p.m. Sunday to a house on Rockland Road by McCoy’s teenage sister. She was the only survivor of the vicious attack that left her mother, a younger sister and a brother dead.

According to the AJC, police retrieved a knife on Sunday that they believed be the “primary weapon” based on the “preliminary investigation, interviews and statements from the suspect,” however over 12 hours after the 911 call was placed, a reporter found a second bloody knife on the front porch of the brick ranch where the attacks happened.

The knife was under a chair but in plain view. Glass from the broken window was scattered on the porch and a slashed window screen appeared to have been flung onto the steps.

“There is no question that this additional evidence should have been collected when the crime scene was processed,” Parish said. “The department will look into this oversight and take appropriate action.”

“I’m not understanding how they missed it and it was right on the porch. It had to be the murder weapon but I just don’t understand how DeKalb County missed that,” neighbor Lashonda Nelson said when she learned the knife was still on the porch.

This error could possibly cause evidentiary problems once the case reaches trial.

“It’s inexcusable and unexplainable and it shouldn’t have happened,” veteran defense attorney Steve Sadow said.

Police arrested the 21-year-old as he was walking away from the family home Sunday evening.? McCoy listed the Rockland Road home in jail records as his residence even though there was a restraining order prohibiting him from being in contact with his family.

McCoy was booked into the DeKalb County jail early Monday on three counts of murder and one charge of aggravated assault and according to court records, there is a long history of family violence.

McCoy has been arrested six times prior to Monday, including twice for allegedly violating family violence orders.? All the cases were before DeKalb County judges.

The first arrest was in 2007 when McCoy was sentenced to 12 months’ probation for burglary, but that case did not involve family violence.

Last May 26, McCoy pleaded guilty to violation of a temporary protective order and was put on probation for a year and ordered to have no contact with the victim.

McCoy pleaded guilty last Sept. 8 to disorderly conduct and was sentenced to 23 days of confinement and 12 months probation.

Then on Dec. 8, McCoy pleaded no contest to family violence battery, disorderly conduct and criminal trespass. He was sentenced to 14 days in jail and two years probation.

He was ordered on Dec. 21 to undergo a mental health evaluation.

He also was told he could have no contact with the victim, a different woman, and to attend 12 anger management classes.

His last previous arrest was on Jan. 8 on a criminal trespass charge. Court records show McCoy pleaded guilty and was sentenced to 12 months probation. He also was sentenced to jail time but received credit for the 67 days and was released on March 16, the day he enter the plea.

It’s so sad that this couldn’t have been prevented. This dude obviously had severe emotional issues that even his mother couldn’t handle.
