A North Carolina resident has been detained following a fatal high-speed, head-on crash that resulted in the death of a sheriff’s deputy, according to state law enforcement officials.

Authorities from the Forsyth County District Attorney’s Office have charged 19-year-old Bryan Castillo with second-degree murder. Originally, he faced charges of misdemeanor death by vehicle, reckless driving, speeding, and driving on the wrong side of the road.

The tragic event unfolded over the weekend, claiming the life of 24-year-old Deputy Kaleb Mitchell from the Forsyth County Sheriff’s Office, as detailed in arrest warrants reviewed by Law&Crime.

The legal documents provide limited specifics about the incident, offering a broad overview without an in-depth narrative.

According to the warrants, on Saturday afternoon, Castillo was driving a Chevrolet pickup truck at an alarming speed of 100 mph along Walnut Cove Road in Walkertown, a small town approximately 10 miles north of Winston-Salem.

Officials highlighted that the legal speed limit on that particular stretch of road is 55 mph.

At some point during the journey, Castillo crossed over the center line, veered into oncoming traffic, and slammed into Mitchell’s vehicle, which was heading south, according to statements issued by the North Carolina Highway Patrol and the Sheriff’s Office.

Mitchell was rushed to nearby Atrium Health Wake Forest Baptist Hospital, where he was pronounced dead shortly after his arrival.

The original arrest warrant on the misdemeanor homicide charge juxtaposes the pickup truck’s alleged rate of speed with the speed limit and says: “This violation was the proximate cause of death.”

The arrest warrant on the more egregious charge alleges simply and in a single line: “On or about the date of offense shown and in the county named above the defendant unlawfully, willfully, and feloniously did murder Kaleb Mitchell.”

On Tuesday, a judge said Castillo could face life in prison without the possibility of parole, according to a courtroom report by Winston-Salem-based ABC affiliate WXLV.

The upgraded charges were filed the day after the initial slate of charges. During a press conference this week, authorities said the new charge was based on an additional investigation.

“It’s a very sad day for the people of Forsyth County,” Forsyth County District Attorney Jim O’Neill said during the press conference.

While the deputy’s death has shaken the community – and elicited a string of eulogies from numerous law enforcement agencies and elected officials – the legal response has played out in typical fashion.

“This defendant is being treated the same way he would be treated if Deputy Mitchell had been a non-law enforcement officer,” O’Neill said.

The prosecutor added that the decision to charge the defendant beyond the misdemeanor offense is due to the legal concept of “malice.”

“You understand that the individual charged here is charged with driving in excess of 100 miles per hour on the roads here in Forsyth County,” O’Neill went on. “That’s an abandonment of the social obligation we hold for one another.”

Mitchell began working in law enforcement in 2022 with the King Police Department, a spokesperson for the department told Police1, an online law enforcement news outlet. Mitchell moved over to the Forsyth County Sheriff’s office in the spring of 2025.

The deceased deputy leaves behind a wife, a son, and an unborn daughter, according to Forsyth County Sheriff Bobby Kimbrough.

“The condition that has been created here is that there’s a wife without a husband, there’s a son without a father, a mother without her son, a community without a first responder, a 24-year-old young man that is no longer a part of this community,” the sheriff said.

Castillo is being detained in the Forsyth County Detention Center without bond.

He is next slated to appear in court on March 19.
