BRISTOL, Tenn. -- Hours before a black Army veteran shot 12 officers at a Black Lives Matter protest in Dallas, another former Army soldier was accused of shooting indiscriminately at passing cars and police on a Tennessee highway.
And like the Dallas sniper, Lakeem Keon Scott said he was motivated to act in response to police violence against African-Americans, authorities said Friday.
One woman died and three others, including a police officer, were wounded Thursday morning in the Tennessee rampage, one of several spasms of violence across the country this week amid boiling tensions over policing and race.
Officers also have been targeted in Georgia and Missouri in the aftermath of police killings of black men in Louisiana and Minnesota, and now the Dallas attack, which killed five officers and wounded seven more. Other departments report being bombarded with threats; some are now requiring officers to patrol in pairs.
Civilians also have been caught in the fray. The woman who died in Tennessee was a newspaper carrier, driving down the highway.
The Tennessee Bureau of Investigation announced that its preliminary investigation revealed the suspect, a 37-year-old black former soldier, was troubled by the other incidents. All those shot were white, police said.
Scott's cousin, Sarah Scott, said she is so close to him he calls her "sister." She said she is shocked by the allegations.
"He's into his culture, he really is; but never would he hurt anybody," she said. He's an "open, big-hearted person."
Scott -- allegedly armed with an assault rifle, a pistol and a large amount of ammunition -- was wounded in a shootout with police early Thursday and remains hospitalized in serious but stable condition.
Police were not able to interview him until late Friday morning, the TBI statement said.
Also Friday in south Georgia, police said one officer was ambushed when called to an apartment complex to investigate a report of a break-in. Another officer was fired upon by a motorist north of Atlanta. And just outside St. Louis, police say an officer was ambushed during a traffic stop.
Scott, who has no criminal history, grew up in New York City and moved to Tennessee fairly recently. His cousin said he has relatives in Tennessee and likely moved there because of a lower cost of living. She said he was in the Army but was injured at some point, collected disability payments and did not have a job.
Army spokeswoman Lt. Col. Jennifer Johnson confirmed he served from January 1998 to June 1999. He was a private in the 5th Battalion 5th Air Defence Artillery Regiment, stationed in South Korea.
One of Scott's brothers, Gerard Griffin, said Scott has three brothers and two sisters and often acted as their "protector."
Griffin said his brother "was a little angry" when he came back from the military.
"He seemed to be getting more and more frustrated with the condition of black people in America," Griffin said.
Scott's neighbour, Alan Lavasser, who is white, said he will never believe the incident was motivated by racial tension over police violence. He said Scott was always nice and friendly.
Lavasser and his wife moved in two years ago and Scott already lived there, he said. They developed a friendship. Lavasser said he would give Scott rides because he didn't have a car, and Scott would stop by and bring them food.
He called Scott a "nice all-around person" who "would do anything for anybody."
"There are a lot of people trying to say this was racially motivated," he said. "I will never believe that, never, because he was always nice to me and my wife and everyone around here. No way I would ever believe that it was racially motivated."
Law enforcement said in a statement that "a thorough understanding of his motivation for this incident remains central to the ongoing investigative work."
Newspaper carrier Jennifer Rooney, a 44-year-old mother of two, was struck by a bullet as she drove to pick up papers for the morning delivery. The Bristol Herald-Courier reported that her car careened over a median and crashed through a chain link fence.
"I don't think she had an enemy in her life," her husband, David Rooney, told the newspaper. "She was the type of person that could have a disagreement with someone and 10 minutes later turn around and help them, and that rubbed off on everybody who she came in contact with."
The wounded included the longtime front desk clerk at a Days Inn hotel, Deborah Watts, who was in serious but stable condition. Investigators say Scott fired first at the hotel.
"She is like a family to us," said Days Inn owner Kiran Patel. "It's horrible. I don't know how to explain how horrible."
David Whitman Davis was also injured by flying glass from the gunfire, the TBI said.
Officer Matthew Cousins was hit in the leg. He was treated for superficial injuries and released.
Scott was stuck by the officers returning fire.
"Don't get me wrong, everything he did was wrong," Griffin said about his brother. "I ain't condoning nothing he did, at all. But frustration, we can all understand that."
