Erika Kirk, the widow of conservative activist Charlie Kirk, waved to supporters Thursday evening as her husband's casket was transported to a chapel in Arizona after his body was flown back from Utah on Air Force Two.

Erika Kirk, 36, dressed in black and wearing sunglasses, was greeted by mourners waving American flags as a motorcade escorted her from Phoenix Sky Harbor International Airport. Vice President J.D. Vance and his wife, Usha Vance, accompanied the coffin on the flight and were with Erika as she deplaned.

National Guard members were seen carrying the mahogany coffin on and off the aircraft. Officials said Charlie Kirk's two young children and his parents, who witnessed the shooting on Wednesday at Utah Valley University, were also on the flight. President Donald Trump said he has spoken with Erika Kirk and described her as "devastated, absolutely devastated," adding that he planned to attend a funeral planned for next week.

Authorities announced late Thursday that a suspect had been taken into custody in Utah. The individual, identified by multiple sources as 22-year-old Tyler Robinson of Utah, was arrested after a tip that investigators said came from the suspect's father, who told authorities his son had confessed. Law enforcement officials and the president described a rapid investigation that included review of surveillance footage and tips from the public. Trump said on Fox News that "I think with a high degree of certainty we have him in custody."

Officials at a Thursday night press conference said the suspect will face the death penalty if convicted. Investigators have not publicly released a motive, and authorities earlier this week said evidence at the scene included ammunition engraved with political language. The top FBI agent in Salt Lake City, Robert Bohls, said investigators view the shooting as a targeted attack, calling it "a targeted event."

Charlie Kirk, 31, was addressing a crowd estimated at more than 3,000 people at an outdoor event on the Utah Valley University campus on Wednesday afternoon when a single shot struck him in the neck. Video of the attack circulated widely on social media. Witnesses described panic and chaos as attendees fled the area after the shot.

Investigators believe the fatal shot was fired from the rooftop of the Losee Center, about 200 feet from where Kirk had been speaking under a tent. Surveillance footage released by authorities shows a figure on top of a roof leaping from the building and sprinting into a nearby neighborhood after the gunfire, according to officials.

A manhunt for the suspect stretched more than a day, during which authorities offered a $100,000 reward for information leading to the arrest. Law enforcement sources said the suspect was taken into custody in Utah late Thursday. He remained in custody and was being questioned by investigators on Friday morning, officials said.

Vance, who accompanied the coffin on the flight, paid tribute to Kirk on Thursday, calling him a "true friend" and saying he was the kind of person who would remember what others told him. Usha Vance was photographed putting her arm around Erika Kirk as the two women walked off the aircraft, a gesture that reflected the tightly wound grief and support surrounding the transfer of remains.

Officials said emergency personnel, campus police and federal agents have continued to review ballistics evidence, surveillance video and witness statements as part of the ongoing investigation. Authorities cautioned that details remain under active review and that formal charging decisions rest with prosecutors.

Charlie Kirk built a national profile as a conservative activist and commentator and leaves behind his wife and two young children, a three-year-old daughter and a 16-month-old son. The killing has prompted an outpouring of public attention and has drawn federal resources, including FBI involvement, to assist local investigators.

As plans for a funeral proceed next week, local and federal officials said they will continue to gather evidence and to coordinate on security and investigative steps. Public officials and aides emphasized the preliminary nature of some details and urged patience as authorities work to complete interviews and forensic analysis.
