Henry Jonathan Valencia, 23, was charged with second-degree murder in the death of Nosiah Santos, according to the Marion County Sheriff’s Office. He was taken into custody Friday by a Major Crimes detective and is being held at the Marion County Jail without bond.

Deputies responded to the Petro gas station near Highway 318 and Interstate 75 around 2:24 p.m. on May 30 following reports of a shooting. When they arrived, they found Santos suffering from a gunshot wound. He was transported by Marion County Fire Rescue to a local hospital, where he later died from his injuries.

Investigators said Valencia and Santos, who were in a relationship, arrived at the gas station together. 

An argument broke out after Valencia became upset that Santos had been communicating with other men, according to witness statements and evidence gathered by detectives.

He then reportedly struck Santos multiple times in the head before fleeing the scene and returning to Jacksonville.

Valencia was identified as the suspect during the investigation and arrested without incident.
