A man admitted Thursday to robbing 14 hotels in New Jersey and New York and could be sentenced to life in prison for shooting a gun during one of the holdups, officials said.

Tremone Burnett, 46, of Orange, pleaded guilty to conspiracy to commit robbery and threaten physical violence, and using a firearm during a crime of violence, U.S. Attorney Craig Carpenito announced.

Burnett robbed the following hotels in 2014:

Howard Johnson, Newark: April 24

Comfort Suites, Woodbridge, May 7

Marriott Fairfield Suites, Parsippany, May 9

Best Western, Rockaway, May 9

Crowne Plaza, Paramus, May 9

Extended Stay America, Secaucus, May 31

Sheraton, Weehawken, May 31

Howard Johnson, Airmont, NY, June 4

Comfort Inn, Edison, June 4

Marriott, Lebanon, June 8

Hilton Garden Inn, Nanuet, NY, June 13

Hotel Executive Suites, Carteret, June 15

Fairfield Inn, Newark, June 15

Comfort Suites, Newark, June 19

Burnett had a handgun when he robbed each hotel and fired it during the Weehawken Sheraton robbery, authorities said.

During five of the robberies, he used zip ties to tie the hands and feet of hotel employees, court records showed.

Officials did not say how much money was taken during the robberies, but when he was first charged in 2014 for robbing six hotels, he made off with $2,850, safety deposit boxes, employee paychecks and an ATM machine.

The robbery count has a maximum penalty of 20 years in prison and the firearm charge carries a minimum sentence of 10 years or a maximum of life in prison.

Burnett is scheduled to be sentenced on Dec. 18.
