The Boston Globe first made the connection of the Tsarnaev brothers to the murders on April 22, 2013, after the
Boston Marathon bombing.
ABC reported that authorities believe Tsarnaev may have been responsible for the triple homicide. Investigators on the Boston Marathon bombing case said Tamerlan Tsarnaev visited Dagestan and neighboring Chechnya for six months following the date of the Waltham murders. After the Marathon bombing, a
Planet Aid driver found discarded fireworks in the Planet Aid donation bin in the parking lot of a restaurant, Gerry's Italian Kitchen, that has been connected in other ways to the Waltham murders case and to the Tsarnaev brothers. Tsarnaev had been a regular visitor at Mess's apartment where the murders took place, and authorities believe that they were roommates for a time. Both men were boxers and spent hours training and sparring together, starting in 2009. Ray said: "Tam wasn't there at the memorial service, he wasn't at the funeral, he wasn't around at all ... And he was really close with Brendan. That's why it's so weird when he said, 'I don't have any American friends.'" One of Mess's relatives confirmed that Tsarnaev was not at Mess's funeral or memorial service. On May 10, 2013, Massachusetts investigators were reported to have forensic evidence placing the Tsarnaev brothers at the crime scene. They said that he implicated both himself and Tamerlan Tsarnaev in the murders during the questioning and was beginning to write a formal statement when he asked to take a break and then suddenly attacked the FBI agent. The agent sustained minor injuries requiring
stitches. The FBI established a post-shooting incident-review team to investigate the shooting.
Time of the murders Based on cell phone usage, police believe the killings took place on the evening of September 11. A call was placed at 8:54 p.m. from Weissman's cell phone to Gerry's Italian Kitchen, a Watertown restaurant, for delivery of three dinner entrees. When a delivery woman arrived at 9:14 p.m., there was no answer at the door, and no one answered when the restaurant called Weissman's cell phone. == See also ==
