D.C. police and U.S. marshals arrested 88 people wanted in paternity support cases following a three-day joint operation, law enforcement officials have announced.

One of those arrested included Yonas Tewolde, a suspect in a fatal shooting in Boston last year, U.S. marshals said.

Tewolde, 29, was arrested at the Marriott Courtyard Washington Embassy Row, 16th Street and Rhode Island Avenue NW, after marshals received a tip from their taskforce in Boston.

The operation, conducted from June 15 to 17, involved about 50 Metropolitan Police officers and deputy marshals from the Superior Court of the District of Columbia.

“We want to ensure that these parents take responsibility for supporting their children,” Police Chief Cathy L. Lanier said in a statement.

The sting was part of an ongoing effort to reduce the number of outstanding warrants in D.C.

In May, D.C. police and federal marshals arrested 107 people. A spokesman for the marshals said another operation targeting domestic violence warrants is being planned for July.
