Man charged with killing 3 women and attacking a 4th

A New Jersey man already charged with killing two women has been charged with killing a third. Authorities say a fourth survived an attack.

Prosecutors say Khalil Wheeler-Weaver was indicted by a grand jury in the deaths of the three women between September and November. The 20-year-old also is charged with sexually assaulting them. He previously pleaded not guilty to charges he killed two women.

Defense attorney Shevelle McPherson said in December the evidence was circumstantial. She hasn't returned a phone message left Monday seeking comment.

Wheeler-Weaver is charged in the deaths of 20-year-old New Jersey City University student Sarah Butler, of Montclair; 33-year-old Joanne Brown, of Newark; and 19-year-old Robin West, of Philadelphia.
