The first two episodes aired last night on A&E - I think it's going to be 5 episodes. It covers 11 unsolved murders of girls in the 70's between Houston and Galveston. The first episode opens Edward Harold Bell, who's an Aggie and was in the band, confessing to the murders to a journalist with the Houston Chronicle. He is already in jail for another murder and sex crimes. He seems to be quite crazy, I believe the rest of the series is going to try to determine if what he claims to have done is true.
