Knife Found Blocks From Where Houston Boy Was Fatally Stabbed, Police Confirm

— -- More than a week after an 11-year-old boy was stabbed to death in Houston, police say they have obtained a knife found "a number of blocks" away from where Josue Flores' body was discovered.

Police, however, are cautious to call this a break in the case.

"We will take it into our property room and do some tests to see if there was a possible link" to Josue's slaying, Houston Police Department spokesperson John Cannon told ABC News today. "It could be involved in this incident, or any other incident. It's just a found piece of property."

Cannon confirmed the knife was spotted on Wednesday in a storm sewer drain by a female passerby.

Police said the Marshall Middle School student was fatally stabbed around 4:45 p.m. on May 17 near the city's Northside neighborhood, where Josue lived and went to school. He'd reportedly stayed late at school that day to attend a science club party.

Authorities released a resident's home-security surveillance footage Tuesday showing Josue's journey home from school moments before he was brutally killed. The incident, which allegedly occurred two blocks away from where he was filmed, was out of range of the surveillance camera.

According to police, witnesses said they "heard loud screaming" and saw the sixth-grader struggling with someone who eventually ran off.

His attacker is described as a black male, 25 to 30 years old, about 6 feet tall and weighing 180 to 200 pounds. Police said he had short hair and was wearing a black shirt, black pants and had a green jacket over his shoulders at the time of the attack.

Investigators are still awaiting results on DNA evidence.

"I wake up believing it's just a horrible dream, that I'll wake up and be able to see my brother again, talk to him about this," Juan Flores, Josue's brother, told ABC News Houston station KTRK. "When the burial is over it's something I have to accept, that it's reality."

Josue's funeral was held Tuesday.

"This is a monstrous crime -- and I say that not just as district attorney but as a mother," Harris County District Attorney Devon Anderson said Monday at a news conference. "There is a monster who is out among us. You may know who he is...your conscience needs to be your guide."
