JACKSONVILLE, Fla. -

Police in Jacksonville have arrested a 23-year-old man in the killing of a cab driver on the Northside earlier this month.

Rohbanni Wilson is charged with murder in the shooting death of 43-year-old Stuart Carson.

Carson was sitting in his Gator City Taxi cab on West 27th Street at about 7:45 a.m. June 7 when he was shot and killed.

Police said Wilson became a person of interest, and through evidence obtained from a search warrant and from witnesses, he was identified as a suspect.

Wilson was located by the U.S. Marshals Service on Wednesday in the 1200 block of Mayport Landing Circle in Atlantic Beach. Wilson lived in an apartment one block away from where Carson was killed.

Investigators said they did not know the motive for the killing.

They said this killing of Carson was not related to the stabbing and robbery of another cab driver in the Moncrief area three days later.

"I'm being a little vague with you guys and there's a reason for it," said Chief Adam Brown, of the Jacksonville Sheriff's Office. "Even though we have charged the suspect with the one count of murder, the investigation is continuing and is still active. We're getting more information in reference to the case, so I cant really go into detail about how we found him or what led up to it. But we have physical evidence, we executed a search warrant where we obtained more evidence, and we also have witness testimony."

Carson's family said they are relieved to know an arrest has been made, but they are still coping with their loved one's death.

"Horrible. Up until yesterday, we finally got a chance to be excited about something and happy about something," Kelly Redington, Carson's wife, said of the arrest.

Wilson made his first appearance in court Thursday morning and was ordered held without bail. His next court date is July 10.

Carson's family showed up at Wilson's first appearance.

"As soon as I walked in, he looked right at me and I gave him a dirty look, and I didn't know if that was him but," Redington said.

Kelly Redington Carson described that moment when she saw Rohbanni Wilson in court Thursday morning, the man charged with shooting and killing her husband, Stuart, nearly two weeks ago. Carson told Channel 4 that she was not prepared to hear that Wilson was a Sex Offender.

"Me, my sister, and my cousin all looked up his name on Google and we found him," explained Kayla Carson. "We started reading that, we thought, oh my god, so we ran out and told my mom, my aunt, and everyone."

Records show Wilson was arrested in 2010 for having sex with a person older than 12, but younger than 16. Wilson was also arrested for petty theft in 2010. In 2011 he was arrested and charged with violating his probation and later that year he was charged for failing to report his name or residence change as a sex offender and resisting arrest.

Wilson is now being held without bond inside the Duval County jail. Carson's family said although they're relieved but, moving forward is still hard without Carson.

"I have to figure out where to go, how to do it without their daddy here. At least he's in jail," said Kayla Carson.
