HALIFAX, N.C. — Two men have become the second and third suspects charged with murder in the deaths of four elderly people shot while playing cards in August, reports CBS affiliate WNCN.

Keyon Quarice West, 23, and James Edward Powell, 25, both of Roanoke Rapids, were charged with four counts of first-degree murder in the Aug. 21, 2017 deaths of Janice Harris, 72, James Harris, 88, James Whitley, 76, Peggy Whitley, 67. The victims, two couples, were killed during an apparent home invasion, according to police.

Matthew Simms, of Enfield, was arrested in October and is also charged in connection with the quadruple killing. Simms was awaiting trial on a separate killing at the time of the slayings in Enfield, but had bonded out and then failed to appear for court, according to online records.

Powell was charged soon after he was arrested in connection with a separate killing, which occurred this past Saturday in Roanoke Rapids, where one man died and another was critically injured in a shooting.

One of the victims, James Harris, was registered to run a firearms business from the home where the killings happened.
