Possible Murder Weapon In 4-Year-Old Boy's Slay, Video Of Kidnapping Found

Dallas police have found a weapon that might have been used in the gruesome murder of a 4-year-old boy who was found lifeless on a Dallas neighborhood street last week. A surveillance video that captured the kidnapping of the child has also been recovered.

Cash Gernon's body was found eight blocks away from his home Saturday around 7:30 a.m. He was lying in a pool of blood and was missing a shirt and a shoe at the time. The child had been stabbed with an "edged weapon" multiple times, police said.

According to court documents obtained by CBS 11 News Monday, a possible murder weapon was found. Police are said to have recovered "a tissue paper in a bathroom that had blood drops on it. A small pocket knife was also located and seized," the outlet said.

Authorities also found footage that shows a man lifting Gernon from his crib and carrying him away around 5 a.m., reported NY Daily News. Gernon was taken from the home of Monica Sherrod, the partner of the child's biological father, where he was living along with his twin brother.

Police identified the man in the video Sunday as 18-year-old Darriynn Brown. He is currently facing kidnapping and theft charges. Police are awaiting further forensic analysis to add on more charges. They are also building a case against Brown.

The suspect's mother told CBS 11 News that her son is not capable of committing such a violent act despite having mental health issues. But according to their neighbors, the teenager has been known to cause trouble in the area.

Police have neither determined nor confirmed any motive behind the killing.

"Even us as police officers, we are shocked. We're very angry about what has happened to the small child," Dallas police Executive Assistant Chief Albert Martinez said as per CNN.

Kamron Moori, 18, who lives at the home from where the boy was taken, said the child was the "sweetest boy" and the attack was unmotivated. "No reason for none of this. It's not from revenge, not from hate, not from none of that," Moori told KXAS-TV.

Gernon's twin brother was taken by Child Protective Services and returned to their biological mother, who had been searching for the boys for an extended period, Dallas police said.
