BUFFALO (WKBW) A Buffalo City Court Judge decided on Friday that the case against 13 year old Jean Sanchez, accused of second degree murder, will now go to a grand jury based on a confession from the teen that he killed 13 year old Ameer Al Shammari by strangling him.

A Buffalo Police homicide detective was questioned, revealing that he interrogated Sanchez, who confessed to the murder.

The detective says Sanchez confessed to strangling Ameer with a shoelace from Ameer's sneaker. When it broke, Sanchez used a cord from his own hoodie to allegedly kill the fellow teen.

A big part of this case is expected to be that the District Attorney is charging Sanchez as an adult, something the teen's attorney disagreed with.

"The New York State law is antiquated. It's 30 years old and it was written before we knew a lot more about the brain, and it bears no relation to science," defense attorney Paul Dell said.

"This is aberration of conduct. Most 13 years olds don't do what this thirteen year old is alleged to have done," Erie County District Attorney Frank Sedita said.

Sanchez will be held at a juvenile detention center until his next court date.

The defense attorney did make several attempts to argue that the statement from his client should not be admissible in court. That fight is expected to continue as this case moves forward.
