A fourth suspect has been arrested in the killing of a woman and the wounding of her 12-year-old daughter in August.
Stephanie Cousins, 49, was arrested Friday and charged with murder with a deadly weapon, robbery with a deadly weapon and conspiracy to commit murder.
Police said Cousins arranged a drug deal with 28-year-old Derecia Newman and her boyfriend, Cornelius Mayo, on Aug. 7 at Newman's apartment in the 5600 block of Meikle Lane, near Christy Lane and Lake Mead Boulevard.
According to the report, Cousins went to Newman's apartment with three others, including Willie Darnell Mason, 27, and David James Burns, 19.
Newman answered the door and Cousins handed her $20. Burns and Mason then entered the apartment and Burns shot Newman and her daughter, De'Vonia, as Mason searched the house for money and drugs, according to the report.
Police said the woman alleged to be the getaway driver, Monica Martinez, 39, was arrested soon after the shooting.
Burns and Mason were arrested in September in San Bernardino, Calif., by Las Vegas police detectives with the assistance of the FBI and the Inland Regional Apprehension Team.
