Court records reveal details on Marty Cobb's murder and alleged killer's past

Posted: Updated:

The teen accused of killing 8-year-old Marty Cobb and allegedly sexually assaulting his sister is now facing a list of charges.

Monday, a Richmond grand jury indicted Mairese Washington on second-degree murder, malicious wounding and strangulation charges. After court documents were opened up to the public Monday, we're learning more about the crimes that led up to the death of a little boy now known as a hero.

Those records mean light is finally shed onto the tragedy of May 1. Documents uncovered with the indictments tell the story. That night two months ago, Marty Cobb's sister told police she and Marty were playing on the railroad tracks behind their Brandon Road home in South Richmond. The girl told detectives Marty "was killed with a log and stomp on by a known suspect." The statement goes onto say that suspect, now identified as Mairese Washington, "beat on and strangled her with his hands and a stick." Family members told NBC12 at the time it was an attempted sexual assault.

It's not the first time Washington has been in trouble with the law. NBC12 was first to tell you about the 2010 incident where he was ordered into a mental health facility after bludgeoning a three-year-old with a hammer.

Now, we've uncovered a lengthy history of criminal charges dating back to when Washington was just 12. Most recently, the teen has probation violations pending in Chesterfield, where his father lives. Then, there are assault and battery and assault on a law enforcement officer charges. Both say the facts are sufficient to find guilt, but are still pending. Also last year, Washington was found not guilty on an aggravated sexual battery charge in Richmond. Other counts we found were dropped or dismissed.

NBC12 legal analyst Steve Benjamin says now that Washington has been indicted in Circuit Court in this incident, many of the questions the public has been asking should be answered.

"The right to a public trial is not only a right that belongs to the accused, it's also our right as the public," he explained.

We've also learned Washington was ordered to undergo a mental health evaluation.

"One question might be whether he is capable of assisting in his own defense," Benjamin added. "That's called competency. Another question might be what was his mental state at the time of the offense."

The evaluation is one of two court records that right now are sealed and being kept from public view.

Washington's next court date is scheduled for July 31, where a judge will hear arguments on motions.
