A deputy part of a U.S. Marshals task force operation died Thursday after he was shot by an “armed and dangerous” man at an Illinois hotel, police said.

“Unfortunately, we were just notified that the McHenry County deputy has passed away from his injuries,” Illinois State Police Trooper Sean Ramsey said in a press conference streamed on Facebook by WMBD.

The McHenry County Sheriff’s Department also confirmed on Twitter that the deputy “passed away,” identifying him as Jacob Keltner.

“Deputy Keltner was shot earlier this morning while attempting to serve an arrest warrant with the U.S. Marshalls Great Lakes Regional Fugitive Task Force,” the department said.

Keltner, 35, was a 12 1/2-year veteran of the department, according to The Associated Press.

Floyd E. Brown, 39, who was already wanted on several warrants, allegedly opened fire at law enforcement officers who had descended on an Extended Stay America in Rockford about 9:15 a.m. Thursday. Brown shot a woman inside his hotel room before jumping out of the window, police said.

Brown, believed to be carrying a rifle, was later located on I-55 between Bloomington and Springfield. Officials said they are negotiating with Brown after he crashed his vehicle and barricaded himself.

The suspect remains in his car and a perimeter has been established, Ramsey said. Authorities are “attempting to negotiate his exit from that vehicle and take him into custody peacefully,” he said.

“We’re kind of at a standstill,” Ramsey told reporters, adding that the suspect hasn’t engaged in any communication except for opening and closing his car door multiple times.

Floyd E. Brown, 39, is accused of shooting an officer who was part of a fugitive task force.
