Last week, another strange link emerged between the accused Boston bomber and the triple murder case. Investigators were called to the parking lot of Gerry's Italian Kitchen on Belmont Street in Watertown. A Planet Aid driver had stumbled upon discarded fireworks in a donation bin there. Law enforcement sources told ABC News that the gunpowder had been emptied from the fireworks and the shells discarded in a shopping bag inside the bin. Investigators put the bins on a flatbed truck and drove them away as possible evidence in the bombing case.
Gerry's Italian Kitchen also surfaced in the triple murder case.
The last time anyone is known to have heard from the three men was at 8:54 p.m. on Sept. 11, when someone called Gerry's on Weissman's cell phone and ordered meatballs, a chicken cutlet and a side order of sausage. When a delivery woman arrived twenty minutes later there was no answer and no one picked up when they tried to call Weissman's cell phone.
The following day the three men were found with their throats slashed, their bodies mutilated and covered with marijuana. Police were perplexed because the drugs and $5,000 were not taken from the blood-soaked scene and there was no sign of forced entry. At the time the bodies were discovered, local prosecutors said "it does look like the assailants and the decedents did know each other. We have no evidence of a break in the apartment."
A source close to the investigation told ABC News they are trying to determine whether Tsarnaev once worked as a pizza delivery driver at Gerry's Italian Kitchen. The manager and employees of the eatery said in repeated interviews that he had never worked there.
In the aftermath of the Boston bombings, Mess' friends and relatives say they can't let go of suspicions about Tsarnaev.
"It's no coincidence that the last time I saw my friend Brendan alive he was walking out of that fight with that kid Tam,'' Wood said.
Officials in neighboring Somerville told ABC News they are glad prosecutors have started to look more closely at a possible connection.
"After seeing what occurred on Marathon Monday…nothing surprises me anymore,'' Somerville Mayor Joseph Curatone told ABC News. "I hope and I know that law enforcement professionals will dig and we will find out the whole story."
Somerville Police Chief Tom Pasquarello said that the savagery Tsarnaev has been accused of displaying – including the alleged assassination of MIT Police Officer Sean Collier – would indicate that investigators should look more closely at the relationship between the murder victims and the suspected bomber.
"Anyone who would go up to a police officer and has no problem with the cold blooded killing of a police officer would have no problem with that type of murder whether it was over a drug deal or another type of crime,'' Pasquarello told ABC News.
