There is “mounting evidence” which suggests that Boston Marathon bombing suspects Tamerlan and Dzhokhar Tsarnaev were involved in an unsolved triple homicide in 2011, according to Massachusetts investigators.
Forensic evidence from the crime scene matched the brothers’ DNA, and cell phone records put them in the area of the murders on the date they occurred, officials told ABC News.
In the wake of the Boston Marathon bombings, authorities in Middlesex County began to investigate the link between Tamerlan and Brendan Mess – one of the three men killed in the triple homicide.
Mess and two other men were found in a Waltham, Massachusetts residence with their throats slit and their bodies covered with marijuana on September 11, 2011. Tamerlan and Mess were once roommates and practiced boxing and martial arts together.
