15-year-old Belcamp teen charged with murder in stabbing death of his brother

Police responded to a fight between siblings at a home in Belcamp Tuesday night, arresting a 15-year-old teen who stabbed his 18-year-old brother.

On Thursday afternoon, a 911 call to police from a home on Jervis Square in Belcamp alerted them to a stabbing, and investigators noted that 15-year-old Tylek Dayvon Williams showed no emotion as he reported stabbing his older brother with a large kitchen knife during an argument.
 
“I can tell you that he has some type of cognitive disability just based on our interactions with him and his interactions with 911,” said Major William Davis with the Harford County Sheriff’s Office, “There's definitely something going on there.  Obviously, we're not physicians so we don't really know.”
           
18-year-old Gary Bernard Williams III did not survive a deep stab wound to the upper torso, and now his younger brother has been charged as an adult with a series of charges including first degree murder.
           
Just three months ago, police had been called to the house after Tylek had been involved in another incident with someone else in the home, and at that time, they served an emergency petition for a review of his mental status.
           
Harford County State's Attorney Joseph Cassilly says state law mandates the teen be charged as an adult if he committed premeditated murder.
 
“They may have issues, but the issues led to killing somebody, and you don't want to just put them in a position where that happens again and then everybody's looking back at the people that are in charge of the system saying, 'Why didn't you guys do something?'” said Cassilly.
           
The adult charges will keep the teen from clearing a mental health evaluation and avoiding lock up, as investigators try to determine if Tylek Williams knew the consequences of his actions when he took the life of his big brother.
 
“You don't know what's going on.  You don't know what kind of provocation there is, what the issue was between the brothers,” said Cassilly, “I've had wives and husbands stab each other and not mean to kill the other person.  They just wanted to inflict some pain, but they didn't really want to kill the person.  They were grief-stricken.  So, you're not sure what's going on.”
