A man suspected of fatally shooting a sheriff's deputy and wounding a woman at an Illinois hotel was taken into custody Thursday after an hours-long standoff that began when he crashed his vehicle along an interstate highway, authorities said.

Floyd E. Brown, 39, was arrested hours after the crash in central Illinois, State Trooper Sean Ramsey said.

Officers employed flash grenades to disable Brown after trying for hours to negotiate with him to surrender, police said.

Brown, of Springfield, was taken to a hospital to be treated for several injuries. It wasn't immediately known what caused the injuries, Ramsey said.

Brown is accused of fatally shooting 35-year-old Deputy Jacob Keltner, a 12-year veteran of the McHenry County Sheriff's Office in northern Illinois.

Keltner was pronounced dead at a hospital several hours after he was shot, spokesman David Dezane said.

The deputy had served on the fugitive task force for five years, and was married with two children, ABC7 reported.

Brown was taken into custody by Illinois police, officials said.

Prosecutors in Winnebago County had previously issued a warrant with $5million bond against Floyd E. Brown, 39, for attempted murder in the shooting of the deputy.

The Winnebago County State Attorney's Office later authorized the charges of first degree murder.

Authorities said Brown used a rifle to shoot the McHenry County sheriff's deputy and a woman around 9.15am Thursday morning at the Extended Stay America hotel in Rockford, a city about 80 miles northwest of Chicago.

Police said that a 25-year-old woman - described as an acquaintance of Brown - suffered injuries that weren't life threatening after being hit by one of the rounds. She was treated in hospital and then released.





No shots were fired by law enforcement.





The deputy was at the hotel as part of a US Marshal's Service fugitive task force that tried to serve Brown an arrest warrant.

Officers also said there were a number of guests staying at the hotel on all three levels during the shooting. No one else was injured in the incident.

Rockford police Lt Andre Brass said investigators believed Brown was armed when he fled the hotel in a light blue or silver Mercury Grand Marquis.

Brass said Brown was wanted on several warrants when the task force went to the Extended Stay America hotel.

It was later revealed that the warrants included two for burglary, one for failing to appear, and one for a parole violation.

'We just want to end this incident peacefully with his surrender,' Brass said.
