After the death of Boston Marathon bombing suspect Tamerlan Tsarnaev and the arrest of fellow suspect Dzhokar Tsarnaev, members of the families of one of the alleged bombers and one of the victims released statements Friday.

"Tonight, our family applauds the entire law-enforcement community for a job well done and trust that our justice system will now do its job," the family of bombing victim Martin Richard, 8, said in a statement quoted by People.

"Our family wishes to salute the thousands of officers ... who worked and collaborated around," said the Richard family, who also thanked citizens for sharing information and images with the FBI.

Despite their gratitude, the family said the road to recovery for its members and for the 176 others injured will be a long one.

"None of this will bring our beloved Martin back," the family said.

Martin Richard's family members were also injured in the Boston Marathon terrorist attack Monday: His mother Denise suffered a servere leg injury, while his sister, Jane, 7, was rushed to a local hospital for emergency surgery.

Meanwhile, the parents of 24-year-old Katherine Russell, wife of suspect Tamerlan Tsarnaev, released a statement outside their home in North Kingstown, R.I., following the 26-year-old's death, according to the NorthKingstownPatch.

Tsarnaev engaged in a shootout with Boston police early Friday, which resulted in his demise.

"Our daughter has lost her husband today, the father of her child," said his in-laws' statement. "We cannot begin to comprehend how this horrible tragedy occurred. In the aftermath of the Patriot's Day horror, we know that we never really knew Tamerlane Tsarnaev."

According to multiple reports, Russell converted to Islam before marrying Tsarnaev. The couple have a 3-year-old daughter together, Zahara Tsarnaev.

Russell's parents added: "Our hearts are sickened by the knowledge of the horror he has inflicted. Please respect our family's privacy in this difficult time."
