A third suspect was taken into custody Friday in connection with the shooting death of Signal Hill resident in February, authorities said.

Following a months-long investigation, Las Vegas resident Jahi Jackson was arrested on suspicion of murder after detectives located the 19-year-old near Wardlow Road and Pacific Avenue, according to the Long Beach Police Department. Jackson was also booked on suspicion of one count each of carrying a concealed weapon and being in possession of a controlled substance. His bail was set at $2 million.

On the evening of Feb. 2, 31-year-old Nashon Wall was sitting in his car in the 700 block of East Esther Avenue near Poly High School when multiple men approached him, the LBPD said. Police say at least one of the men produced a handgun and fired at Wall, striking him multiple times, authorities said. When officers arrived at around 6:34 p.m., they found Wall unresponsive in the roadway next to his car.

Despite life-saving measures by Long Beach Fire Department personnel and being treated at a hospital for his injuries, Wall died.

Following the shooting, the suspects fled into a nearby apartment complex, prompting a SWAT team to respond and serve a search warrant. Police were able to locate firearms evidence at the apartment complex that night but no suspects, according to the LBPD. Police have not yet identified a motive.

In March, police identified 20-year-old Anaheim resident Saeed Wheeler as a suspect in the shooting. Wheeler, who had already been arrested by the Los Angeles County Sheriff’s Department in an unrelated crime, was charged with one count each of murder, possession of a firearm by a felon and unlawful possession of ammunition. He has since pleaded not guilty to the charges.

Last month, police also arrested 19-year-old Jalen Jackson on suspicion of murder for the slaying of Wall. He has also plead not guilty to the charges, including an additional count of carrying a concealed weapon, court records show. Both Wheeler and Jalen Jackson have remained in custody since their arrest and are due back in court next month for a pre-hearing conference. It is not clear at this time if there is any relation between Jalen and Jahi Jackson.

Detectives will present the case against Jahi Jackson to the Los Angeles County District Attorney’s Office next week for filing consideration. The investigation is ongoing.
