Investigators Eyeing Deceased Boston Bombing Suspect in Unsolved Grisly Triple Murder

(Bridget Driscoll)

On Sept. 12, 2011, the bodies of three men were found in a Waltham, Mass. apartment with their throats slit in a horrific triple murder. One of those victims was reportedly the late Boston bombing suspect Tamerlan Tsarnaev's only American friend. Now, police in a Boston suburb are investigating whether Tsarnaev perpetrated the attack.

It has also come to light that two of the victims were more than likely Jewish. One of the victims was an active member of his Jewish synagogue and another was a graduate of the predominantly Jewish Brandeis University and was buried in Israel, according to reports.

Tsarnaev's friend, Brendan Mess, was found murdered in his Waltham, Massachusetts apartment the day after the 10th anniversary of the September 11 attacks, alongside Erik Weissman and Raphael Teken. Friends say they believe the men were actually killed on the night of Sept. 11, 2011.

All three of the men's throats had been slit, their bodies reportedly cut and covered in marijuana.

While some reports on the slaying noted Mess's friendship with Tsarnaev, the potential Jewish connection was not revealed until recently.

It should also be noted that while Tsarnaev had claimed to consider Mess his best friend, he in fact did not even attend the funeral or memorial service.

"We are looking at a possible connection with the suspect in the marathon atrocity and this active and open homicide in Waltham,'' Stephanie Guyotte, a spokeswoman for the Middlesex County District Attorney, confirmed to ABC News.

Tsarnaev had reportedly been training with Mess, who he claimed was his best friend, in an attempt to transition from boxing into a possible career in mixed martial arts.

The victims, Weissman, 31, Teken, 37, and Mess, 25, had all been lifelong friends. What's more, sources said they were strong men, casting doubt on how all could have been dragged into separate rooms and murdered with apparent ease.

According to WCVB, Weissman was a devout Jew who was active in his synagogue while Teken attended the predominantly Jewish Brandeis University and was buried in Israel. More from WCVB:

Ward 5 Councilor Gary Marchese, a lawyer by trade who represents Harding Avenue, told Wicked Local/Waltham that from everything he’s read about the case so far, he’s not sure there’s a clear connection between Tsarnaev and the triple murder.

"I’d like to put that case to rest for sure and I know the neighbors do too," Marchese said. "And as a city and neighborhood we want to put those murders to rest. But, I don’t see the dots being connected."

Marchese said there were vague connections between the suspects being "potheads" and the victims being alleged drug dealers, but he wasn’t sure the timeline of events was sensible.

"In my gut – and unless there’s more and something comes out – I don’t see him as a connection to that triple murder," Marchese said. "But hey, I hope it rekindles the investigation and opens some other avenues to explore who the killers are."

Since the victims' bodies were allegedly found covered with marijuana, and two of the victims -- Weissman and Teken -- were suspected of dealing marijuana, the triple murder was initially considered to be drug-related.
