MILWAUKEE - Two men accused of brutally murdering a Milwaukee mom and her two young sons pleaded not guilty to the charges against them in court on Friday. Prosecutors say Anthony Barnes and Desmond Laster went with Brittney Roberton to Rachel Thompson's house on February 26th, intending to rob Thompson, but they ended up killing her and her two little boys.

During Friday's hearing, Milwaukee detectives took the stand to describe what allegedly happened that night in Thompson's home - and even these trained investigators had a hard to reliving the tough scene they encountered. Their graphic testimony may be difficult for some to hear.
