“The Department is devastated by her loss,” the Massachusetts State Police posted in a statement on Facebook. “We are eternally grateful for the attempts of everyone involved to assist Trooper Bucci and to save her life.”

“Her selfless act embodies the mission of the State Police to help those in need, a mission that we carry on in her memory,” the statement continue.

Governor Charlie Baker on Friday morning ordered flags “at all state buildings to be lowered to half-staff in Trooper Bucci’s honor,” he said on Twitter.

Lieutenant Governor Karyn Polito sent her condolences to Bucci’s friends and family.

“Our first responders put their lives on the line every day to serve the Commonwealth, risking their safety each time,” she said on Twitter. “Trooper Bucci’s service + sacrifice will forever be remembered.”

Congresswoman Katherine Clark said on Twitter, “Our community has lost a local hero. Trooper Tamar Bucci gave her life while serving others.”

Terrence Reidy, the state’s public safety and security secretary, said Bucci’s death was “the ultimate sacrifice,” and she “will always be remembered for her legacy of protecting and serving others.”

“Her passing is a solemn reminder of the risks and dangers our law enforcement community faces every day; we owe them our deepest gratitude,” Reidy said in the statement.

Attorney General Maura Healey called the loss “devastating.”

“We honor the sacrifice of Trooper Tamar Bucci in the line of duty and send strength to her family and @MassStatePolice brothers and sisters who are mourning this tragic loss,” Healey said in a tweet.

State Representative Tim Whelan said Bucci “is what a hero looks like.”

“May almighty God bring strength to the family and friends of Trooper Tamar Bucci. My family and I will pray for them and for her grieving colleagues on the Massachusetts State Police,” Whelan said on Twitter. “Thank you for your brave service, sister.”

Other public officials like State Auditor Suzanne Bump, Bristol County County District Attorney Thomas M. Quinn III, Suffolk County District Attorney Kevin Hayden’s office, and State Representative Mike Soter all shared tributes on social media and expressed their condolences to Bucci’s friends and family.

Bucci previously worked in the security department at Encore Boston Harbor in Everett, and a company spokeswoman released a statement on behalf of the casino’s owners.

“We, at Encore Boston Harbor, were deeply saddened to wake up to the news of this terrible tragedy,” the statement said. “Our sincerest sympathies and condolences go out to State Trooper Bucci’s family and loved ones.”

The State Police Association of Massachusetts called Bucci “not just a coworker to us” but “our sister.”

“We send our heartfelt thoughts and condolences to the family and friends of Trooper Tamar Bucci and to our brothers and sisters of the Massachusetts State Police,” Lowell police said on Twitter.

A resident of Reading for several years, Bucci graduated from Reading Police Department’s Citizens Police Academy in 2017, the department said on Facebook. The department said it was “lucky to have met this wonderful young lady.”

“She told us she wanted to be a police officer and she stuck with her dreams and became a Massachusetts State Trooper,” Reading police said on Facebook.

Other departments that sent condolences to Bucci’s family and State Police included the Boston Fire Department, Malden Police Department, Worcester Police Department, and the Middlesex County Sheriff’s office.
