Police officers from across the country converged on the nation’s capital this weekend ahead of National Police Week.
The names of nearly 400 officers will be added to the walls of the National Law Enforcement Officers Memorial in Washington this year. Among them are Massachusetts State Police Trooper Thomas Clardy and Auburn police Officer Ronald Tarentino Jr.
Both President Donald Trump and Vice President Mike Pence will be attending Monday's services.
Thousands came to honor the slain officers at the emotional 29th annual candlelight vigil Saturday evening.
"We are here because these men and women have given everything," U.S. Attorney General Jeff Sessions said. "They gave their lives for us."
A full list of events can be found here.
Clardy, 44, was killed on March 16, 2016. He had stopped a car for a traffic violation on the Massachusetts Turnpike in Charlton when his cruiser was hit by another vehicle. The driver who hit him was allegedly under the influence of marijuana.
"It was just really the shock value that was going," Massachusetts State Police Superintendent Col. Richard McKeon said. "It filtered throughout the state police and it was really a terrible day. And I've seen it in other officers and agencies as well."
Tarentino, 42, was shot in the back on May 22 during a traffic stop in Auburn. The suspect was later killed in a shootout after firing at police.
"I told them that it was going to be very, very difficult," Auburn Police Chief Andrew Sluckis recalled. "We had a long road ahead of us, but we would get through it and we would get through it together."
Sluckis added his department is still trying to get through it, nearly one year later.
In all, nine officers were added to the memorial - including Sgt. Charles Bradley of the Cambridge Police Department, who was killed decades ago.
"Present CPD Officer Steve Lyons, through hard diligent work, uncovered Sergeant Bradley’s death on December 13, 1934," said said Jeremy Warnick, public information officer for Cambridge Police. "Sergeant Bradley was killed on duty after being struck by a motor vehicle. It was through Officer Lyons's hard work that he also located Sergeant Bradley's descendants."
Perry Russom will have live reports from Washington, D.C., through Monday.
