Lucas has not yet been arrested and is still on the run.
Jailen Lucas and Kelvin Thomas Jr. were both arrested in connection with the killing of Tarpinian-Jachym, U.S. Attorney Jeanine Pirro announced in early September.
Lucas and Thomas have violent records in family court, Pirro said, noting that they are juveniles.

During a news conference in September, Metropolitan Police Department Chief Pamela Smith said she's confident Lucas will be arrested.
"These two arrests, and a third one pending – I'm confident we'll get the third one – give Eric's loved ones some sense of peace as they continue to grieve a tremendous loss. Eric came to our city with a bright future ahead of him interning in a role where he served the public on Capitol Hill. He deserved an opportunity to return home safely to his family but was senselessly taken from his loved ones," Smith said.
Police said a woman and 16-year-old boy were shot but survived the July 1 shooting that left Tarpinian-Jachym dead.
