The D.C. Metropolitan Police Department has named the third suspect wanted in connection to the June murder of a congressional intern who was shot near a Washington, D.C., metro station.

“The investigation has identified a third and final suspect, 18-year-old Naqwan Antonio Lucas,” the police said in a press release, seeking the public’s help to track down the remaining suspect. “Lucas is wanted on a D.C. Superior Court arrest warrant for First Degree Murder while Armed (Premeditated).”

Reward money of up to $50,000 is currently being offered for information related to the successful arrest and conviction in all D.C. homicides, the Metropolitan Police Department (MPD) stated.

MPD is offering up to $25,000, while the FBI is offering an additional $15,000 and the United States Marshals Service is an $10,000.

Anyone who has knowledge of the whereabouts of Naqwan Lucas should take no action but call police at [phone] or text a tip to the department’s text tip line at 50411, MPD stated.

Authorities announced on Sept. 5 that two teen suspects had been arrested over the murder of 21-year-old Eric Tarpinian-Jachym, who was interning in the congressional office of Rep. Ron Estes (R-Kan.).

A student at the University of Massachusetts–Amherst, Tarpinian-Jachym became caught up in the June 30 shooting and is not believed to have been the intended target. He was hit by four stray bullets, according to the charging documents. A total of 79 cartridge casings were found at the crime scene.

A woman and a 16-year-old were also injured in the gunfire.

The 17-year-olds, identified as Jalen Lucas and Kelvin Thomas Jr., were charged with first-degree murder and will be tried as adults, U.S. Attorney for the District of Columbia Jeanine Pirro told media on Sept. 5 when announcing the arrests.

Pirro noted that the two suspects, already arrested by the FBI, had prior violent criminal records in family court.

During the attack, they were allegedly driving a vehicle that had been stolen in Maryland several days earlier.

“[Jachym] was an innocent bystander who was caught in a violent act that was not meant for him,” Pirro said. “His death is a stark reminder of how fragile life is and how violence too often visits us in the nation’s capital.”

Standing alongside Washington Mayor Muriel Bowser and Metropolitan Police Department Chief Pamela Smith, Pirro said at the time that officials were still looking for a third suspect, but Lucas was not named.

It’s unclear if Naqwan Antonio Lucas and Jalen Lucas are related.

Jalen Lucas and Kelvin Thomas Jr. are being held without bond.
