4-year-old boy found violently murdered in Dallas. Police have arrested an 18-year-old suspect.

A 4-year-old boy was found violently murdered and police have arrested an 18-year-old suspect who might have been caught on video kidnapping the victim.

The disturbing incident unfolded Saturday morning in Dallas when a jogger found the boy's body in the middle of a street.

Dallas police said the matter is being investigated as a murder.

Investigators initially said they believed a "single individual" killed the boy with an "edged weapon" based on the condition of the body.

The woman who said she found the body of the child spoke to KTVT-TV about what happened. She said that she went out to jog that morning because it was such a beautiful day outside. She said she was startled to see the boy lying in the street and called 911.

"That image that I saw, I just can't erase it. To see a child covered in blood in the middle of the street, it's truly traumatizing," said the woman, who added that the boy wasn't wearing a shirt or shoes.

By Saturday evening, police confirmed that they had a suspect in custody, and later identified him as 18-year-old Darriynn Brown.

Brown was initially charged with kidnapping and theft, but officials said they expect to add more charges pending their investigation and forensic analysis.

A woman, who identified herself as the boy's mother to WFAA, told the station that his name was Cash Gernon and claimed that he had been sleeping when he was kidnapped. Police said that the woman was the boy's guardian.

She said that the boy had a twin brother who is in the custody of the state. She also said that she has no idea why Brown allegedly killed the boy, and claimed that they had no prior relationship.

Residents told WFAA that they would see Brown walking through the neighborhood. Court records showed that he lived about a half-mile away from the crime scene with his parents.

"Hard to believe. I don't think he was in his right mind," said one resident named Jose Ramirez.

The boy's guardian claimed that Brown was caught on surveillance video breaking into the back of the home.

Brown was held on a bond of $750,000 for each charge. His mother told KTVT that Brown was innocent and had been framed by the real killer of the child, whom she suspected to be part of his family.
