Prosecutors have charged a third person in a September triple homicide that left two teens and a child dead.
Investigators say Shellana Davis took shell casings from the shooting scene near the Grandview Triangle. Court documents say she went to the victims' house with the man suspected in the homicides, Joseph Nelson, and later watched him kill the three victims.
Prosecutors said an argument between Nelson and 17-year-old Bianca Fletcher led to the shooting. Her 1-year-old child and 18-year-old Shannon Rollins also died.
According to a probable cause statement, Davis told investigators she was summoned into the house by Nelson and witnessed the argument as well as Fletcher falling to the floor after being shot. She said she ran out of the house after hearing a second gunshot but was told to come back inside by Nelson after the gunshots ceased. Davis said Nelson told her to pick up as many shell casings as she could find. She complied and gave 14 shell casings to Nelson, according to the probable cause statement.
Mark Benson is also charged in the case. Prosecutors said he also tampered with evidence.
According to the probable cause statement, Nelson handed Benson a set of car keys and two broken cellphones and told Benson to get rid of them following the homicides. Benson told investigators he threw the items down a storm drain. He also said he and Nelson took a small bag of shell casings and dumped them in a dumpster and that they also sold Nelson's 40-caliber Smith & Wesson handgun to an acquaintance. Benson said they burned a trash bag which contained the clothes worn by Nelson and Davis at the time of the homicides.
Benson also told investigators he was not with Nelson and Davis at the time of the homicides, according to the probable cause statement.
