Authorities have identified the man shot and killed by Prince George's County police officers Monday after he was reportedly threatening residents with a handgun in a Landover neighborhood.

Trayvon Dodson, 19, of the 6500 block of Hansford Street in District Heights, pointed a handgun at a teenage boy, and at least three residents called to report that he was acting strangely as he walked up and down the 1800 block of Ray Leonard Road Tuesday just after 2 p.m., police have said.

Officers arrived in less than a minute, found Dodson and told him to drop his weapon, authorities have said. When Dodson brandished the gun toward them, four officers opened fire, authorities have said.

It is unclear how many shots were fired or how many times Dodson was struck, but he was taken to a hospital in critical condition and later died, police have said.

All four of the officers who fired have been placed on paid administrative leave while the shooting is investigated internall. Police identified them Tuesday as Cpl. Herbert Aiken, who has worked for the department for 10 years; Cpl. Dwayne Smith, who has worked for the department for six years; Officer Richard Clark, who has worked for the department for three years; and Officer Timothy Hancock, who has worked for the department for a year. All four were assigned to the District III station, police said.

Attempts to reach a member of Dodson's family were not immediately successful.

The shooting was the second involving Prince George's police officers in four days. On Friday, a police officer shot and wounded a suspect who backed toward him in a stolen car. The suspect in that case, Terrance L. Nelson Jr., 19, of Southeast Washington, suffered wounds that were not life-threatening and has been released from the hospital.

He was charged with assault and related counts.
