BRISTOL, Tenn. (AP) — A man accused of shooting indiscriminately at passing cars and police on a Tennessee highway told investigators he was angry about police violence against African-Americans, authorities said Friday.

One woman died and three others, including one police officer, were injured in the rampage.

The Tennessee Bureau of Investigation said in a news release that initial conversations with the suspect, 37-year-old Lakeem Keon Scott, revealed he was troubled by several incidents across the U.S.

Scott, who is black, was wounded in the shootout with police, remains hospitalized and has not yet been charged. All those shot were white, police confirmed.

The announcement comes just hours after 12 officers were shot at a Black Lives Matter protest in Dallas by a man who police say declared he was angry about police shootings of black men and wanted to exterminate whites. Five of the officers died.

The shooting spree in Tennessee began around 2:20 a.m. Thursday.

The Tennessee Bureau of Investigation alleges Scott — armed with an assault rifle, a pistol and a large amount of ammunition — fired shots through the window of the Days Inn on Volunteer Parkway.

The front desk clerk, Deborah Watts, was struck and injured. Days Inn owner Kiran Patel said he awoke to the sound of gunfire. His wife called the front desk to see what happened, Watts answered and said she'd been shot. She remains in the hospital in serious but stable condition.

The gunman then turned his fire to cars passing on the highway, investigators say.

Newspaper carrier Jennifer Rooney, a 44-year-old mother of two, was on her way to pick up papers for the morning delivery when a bullet struck her. The Bristol Herald-Courier reported that her car careened over a median and crashed through a chain link fence.

David Whitman Davis was also injured by flying glass from the gunfire, the TBI said.

Three officers with the Bristol Tennessee Police Department arrived and confronted Scott, who fired on them.

Office Matthew Cousins was hit in the leg. He was treated for superficial injuries and released.

Scott was stuck by the officers returning fire. He remains in the hospital in serious but stable condition.

The Tennessee Bureau of Investigation said the investigation is ongoing as they work to understand the shooter's motive.
