The District of Columbia's police department has released the names and mugshots of the three suspects in the killing of a congressional intern in June.

Kelvin Thomas Jr., of Southeast D.C., and Jailen Lucas, of Northwest D.C., both 17, were arrested on Friday in the shooting death of 21-year-old University of Massachusetts Amherst student Eric Tarpinian-Jachym, an intern for Rep. Ron Estes, R-Kan., Fox News reported. They were both charged with first-degree murder and will face trial as adults.

Naqwan Antonio Lucas, 18, of Granby, Mass., is also wanted for premeditated first-degree murder while armed.

The suspects also injured a woman and a 16-year-old boy during the attack, according to the district's Metropolitan Police Department.

A $50,000 reward is being offered for information leading to a D.C. homicide conviction of Naqwan Antonio Lucas.

President Donald Trump cited Tarpinian-Jachym's death, along with the beating of former Department of Government Efficiency staffer Edward Coristine, among the reasons for imposing a federal crackdown on crime in the nation's capital.
