MANHATTAN (AP) — A mother and son each pleaded not guilty to aiding and abetting the first-degree murder of a Manhattan man.

Forty-nine-year-old Christina Love and 33-year-old James McKenith, both of Manhattan, entered their pleas Monday. They are charged in the death of 68-year-old John Burroughs.

Prosecutors allege the pair helped Anthony Nichols of Kansas City, Kan., kill Burroughs last September at his home.

Nichols also is charged with first-degree murder in the death of a Junction City man the same night Burroughs was killed.

Investigators say Love drove with her son to Burroughs’ home and witnessed the stabbing. McKenith is accused of stabbing Burroughs after Nichols allegedly shot him earlier.

McKenith is scheduled to start May 5, and Love’s trial is scheduled to start June 2.
