Police in Maryland said they have arrested two people in the slaying of a transgender woman in Rockville last month.

On April 16 at about 11:49 a.m., Montgomery County authorities found Keyonna Blakeney dead at a Red Roof Inn as a result of multiple sharp force injuries, Montgomery County Police said in a statement. Blakeney and several acquaintances were renting rooms at the Red Roof Inn to engage in prostitution, police said, and she was killed after an argument.

“Someone out there is evil who did this,” Blakeney’s father, Kenny Linton, told The Washington Post last month. “My son was, is, very special. He was kindhearted. He was down-to-earth. He would give you his last if he had it.”

After an investigation, warrants were issued for Arbra Arnie Bethea, 17, of the 4900 block of East Capitol Street SE, and Keith Christopher Renier, 21, of the 4200 block of Fort Dupont Terrace SE, charging them with murder as well as for armed robbery, conspiracy to commit first-degree murder and conspiracy to commit armed robbery, police said. They were arrested by Montgomery County Police and the U.S. Marshals in Washington on Tuesday, and Bethea has been charged as an adult, according to police.
