Tributes are flooding in for William “Billy” Evans, the 18-year veteran of the U.S. Capitol Police who was killed in Friday’s attack at a Capitol checkpoint. Evans is being mourned by lawmakers as a hero and remembered by friends as a caring father, dedicated officer and good-natured jokester.

The country is reeling from the attack, which took place at the north barricade of the Capitol building just after 1 p.m. A suspect rammed his car into Evans and another officer and crashed into a barrier, then got out and started running toward them while wielding a knife, police said.

Two sources who were briefed on the details of the investigation confirm the suspect has been identified as 25-year-old Noah Green. At least one officer shot the suspect, who later died. The second officer, who was not identified, was hospitalized with injuries, and authorities said Friday evening he was in stable and non-life threatening condition.

Evans joined the department in 2003 and was a member of its first responders unit, according to acting U.S. Capitol Police Chief Yogananda Pittman. He is the second member of the force to have been killed in the line of duty this year — Officer Brian Sicknick died a day after insurrectionists stormed the Capitol on Jan. 6.

“We send our heartfelt condolences to Officer Evans’ family, and everyone grieving his loss,” President Biden said in a statement on behalf of himself and the first lady. “We know what a difficult time this has been for the Capitol, everyone who works there, and those who protect it.”

Biden also ordered flags at the White House and all federal buildings to be flown at half-staff until Tuesday evening. Members of Congress, many of whom were in their home states on Friday as the House and Senate are in recess, are also mourning Evans’ death and thanking the officers for their bravery.

House Speaker Nancy Pelosi called Evans “a martyr for our democracy,” while Senate Minority Leader Mitch McConnell said “his name will go down in history for his selfless sacrifice.”

Pelosi also said she had conveyed prayers and condolences on behalf of the House of Representatives to “his mother Janice, with our offer of assistance to her and Officer Evans’ children Logan and Abigail.”

The Evans family is asking for privacy, according to the Capitol Police. Several people who knew him personally and professionally have spoken to the media, painting a picture of a devoted public servant and father of two.

The North Adams, Mass., native turned 41 earlier this year, reported Boston’s ABC-affiliated WCVB.

Jason LaForest, a North Adams City Council member and childhood friend of Evans, described him in a phone interview as a talented athlete and musician who loved to make people laugh, especially with practical jokes and pranks. Evans “had an infectious laugh and an infectious smile,” LaForest said.

Evans had wanted to be a Capitol Police officer since college, LaForest said, adding that he loved the people that he interacted with each day at the Capitol, from coworkers to lawmakers.

And he loved being a dad above all else, LaForest said. The avid golf player and baseball fan instilled in his children a love of sports, and they especially enjoyed mini golfing, playing video games and traveling together. Evans always kept them laughing and capitalized on every opportunity for a joke, he recalled.

“There isn’t a picture of those kids that doesn’t show them not just smiling but smiling broadly, and you know that there’s a laugh behind all of that,” La Forest said. “Billy’s a guy who could make a trip to the dump look like a truly good time, and he certainly made every moment count with his children.”

Evans leaves behind his mother and older sister as well as a hometown where “his death will be felt by many,” LaForest said. He emphasized that while the attack and the formalities to follow loom large in the national spotlight, Evans’ family is processing the loss of a son, brother and father.

Neighbors told The Washington Post that Evans spoke fondly of his children, who were always visibly excited to see him driving into the neighborhood. Reporters from The Post visited the Evans home in suburban Virginia, where colorful gel letters spelled out “Happy Easter” across the front door.

An extended relative, Beth Terranova, told The Post that Evans was a Star Wars fanatic who enjoyed online gaming and rooting for Boston’s sports teams.

Evans graduated from Western New England University in Springfield, Mass., in 2002 with a bachelor’s degree in criminal justice, administrators confirmed to NPR. He was a member of the school’s baseball team, bowling team and campus activities board, university President Robert E. Johnson said in a statement to the community.

“In the past twenty four hours, Billy’s close friends from WNE have been reminiscing about their time with him on campus, describing him as someone who was extremely welcoming and friendly, humble, and always willing to help others,” he added.

Evans’ college roommate, Matt Derry, told WBZ that Evans was active in sports and was well-liked with a lot of friends. He was “always happy, always laughing, just that kind of person,” Derry added.

LaForest told The Berkshire Eagle that Evans was proud to be a U.S. Capitol Police officer.

“He carried his badge everywhere,” he said. “He was just so proud, and his family was so proud of him.”

Terrance Gainer, who served as Capitol police chief when Evans joined the force, told USA Today that Evans was “a wonderful guy” who was “held in high regard by the force and Capitol staff.”

David Popp, McConnell’s communications director, said in a tweet Friday that he often saw Evans at the north barricade when he arrived for work.

“He was so friendly and professional, and seeing him was always a plus,” he added. “Today is a very sad day.”

Kristin Wilson, who covers Capitol Hill for CNN, told the network that Evans was a visible presence on the grounds, especially on the Senate side, and described him as “the kindest person.”

She said Evans always offered up a friendly word or morning greeting, made “bad dad jokes” and seemed to enjoy giving the regulars “some sort of grief,” often asking them why they were there so early or whether they had somewhere else to be.

“Never an unkind word,” Wilson said. “Just a nice, kind word for everybody, whether it was some staffer walking in, or some intern, or a senator. … This one hurts. They all hurt, but this one hurts.”

Five days after a skyscraper-sized container vessel was dislodged from the Suez Canal, the backlog of ships waiting to cross through the Egyptian waterway has been cleared, the canal authority says.

When the 1,312-foot Ever Given ship ran aground March 23, it blocked canal traffic, grinding maritime shipping to a halt at one of the world’s busiest waterways. During the six days the Ever Given remained stuck, more than 400 ships were stranded at the man-made canal, which connects the Mediterranean to the Red Sea.

But after a flotilla of tugboats finally freed the vessel on Monday, traffic resumed. Late Friday, the chairman of the Suez Canal Authority told an Egyptian television station the remaining 61 ships would pass through the canal on Saturday.

Chairman Osama Rabie told MBC Masr that in total, 85 ships were expected to pass through the canal in both directions Saturday, according to Reuters. The canal authority began an investigation Wednesday into what exactly caused the Ever Given to run aground and block the waterway. That investigation should be complete within two days, he said.

Experts say bigger ships have been constructed over the past several decades as demand for consumer products has grown. The Empire State Building-sized Ever Given isn’t an anomaly; more than 100 similarly massive ships are traveling the world’s waterways — with even bigger ones under construction.

Marine-risk analysts have long warned about the concerns of ever-larger ships, Capt. Andrew Kinsey, a senior marine-risk consultant for Allianz, told NPR this week. “We’ve been trying to raise the issue for a very long time,” he said, calling the Ever Given incident “a warning” of things to come.
