A District man awaiting trial on first-degree murder charges in Maryland has been arrested in connection with a year-old Southeast Washington homicide.

On Friday, D.C. police charged Corey Yates, 22, of Southeast, with first-degree murder while armed in connection with the killing of Darrel Hendy. Hendy, 29, was found fatally shot on the afternoon of Sept. 25, 2010, in the 800 block of Southern Avenue.

Yates is the third person charged with first-degree murder in the Hendy case. D.C. police arrested 18-year-old Meeko Carraway last October and 36-year-old Chamontae Walker in April.

According to an indictment handed up by a D.C. Superior Court grand jury, Walker told the other two men that Hendy, a former friend, was trying to kill him. The indictment alleges that the three suspects plotted to kill Hendy, then flee to North Carolina to evade law enforcement.

A jury trial in the Hendy case is scheduled for February, according to online court documents.

Yates, who according to police is in custody at the D.C. jail, had been held in Montgomery County, where he is charged with first-degree murder in the shooting of Doodley Derose, 19.

Derose, a graduate of Kennedy High School in Silver Spring, was shot Dec. 21 in the 1600 block of Hutchinson Lane in the Glenmont area of Montgomery. Yates turned himself in to authorities in January after a warrant for his arrest was issued.

That case goes to trial in January, according to online records.
