A 31-year-old male fatally shot eight children execution style in Shreveport, Louisiana, on Sunday morning — and seven of the victims were the shooter's own children, authorities told the New York Times.The gunman, Shamar Elkins — who was fatally shot following a police chase — had mental health problems and recently had expressed suicidal thoughts, the Times said, citing family members' statements in interviews.'My babies — my babies are gone.'The children ranged in age from 1 to 14, officials told the paper, and seven of the eight were Elkins' own children. A Shreveport Police Department spokesman said he shot them execution style, the Times reported.Elkins also shot two other people, including his wife, who was hospitalized with life-threatening injuries, the paper said, citing officials and relatives.Following the shootings, authorities said Elkins took a car by force, and police pursued him, the Times said. Officers opened fire, and Elkins died, Cpl. Chris Bordelon of the Shreveport Police Department said in a news conference, according to the paper. It's unclear if officers killed Elkins, or if he died of a self-inflicted gunshot wound, the Times said.Shreveport Mayor Tom Arceneaux said it's “maybe the worst tragic situation we’ve ever had," according to the paper.RELATED: Masked men open fire after storming into Chick-fil-A; 1 dead, 6 injured; manhunt under way While police haven't offered a possible motive, the Times said relatives in interviews noted that Elkins recently struggled with mental health and was stressed about his relationship with his wife, Shaneiqua Pugh.More from the paper:Earlier this month, on Easter Sunday, he called his mother, Mahelia Elkins, and his stepfather, Marcus Jackson. Ms. Elkins and Mr. Jackson said in interviews that their son sounded despondent. They said they could hear his children playing in the background during the call.Mr. Elkins told them through tears that he wanted to take his own life. He told Mr. Jackson that his wife wanted a divorce, and that he was drowning in “dark thoughts.”“I told him, ‘You can beat stuff, man. I don’t care what you’re going through, you can beat it,’” Mr. Jackson said. “Then I remember him telling me: ‘Some people don’t come back from their demons.’”Elkins' mother told the Times she didn't know precisely what problems her son was having with his wife. The paper said records indicate they were married in 2024. Elkins' mother added to the Times that her son worked for UPS and had served in the Army.The Army told the paper in a Sunday statement that Elkins served in the Louisiana Army National Guard from August 2013 to August 2020 as a signal support system specialist and a fire support specialist. The Times added that Elkins had no deployment and left the Army as a private.Elkins' mother also told the paper she wasn't extremely close with her son; she had given birth to him when she was a teenager and struggling with a crack cocaine addiction. The Times added that she had a family friend — Betty Walker — raise Elkins, and he and his mother reconnected more than a decade ago.Walker spoke to authorities Sunday, the paper said. While she didn't witness the shootings, Walker said in an interview that Elkins shot his wife several times, including in the head and in the stomach, the Times reported.Walker told the paper she last saw Elkins last weekend when his family came over for dinner, and nothing appeared off with him at the time: “I was getting up this morning to make myself some coffee, and I got the call. My babies — my babies are gone.”The Times, citing records, reported that Elkins had at least two prior convictions, including driving while intoxicated in 2016 and illegal use of weapons in 2019.The paper said a police description of the March 2019 incident notes that Elkins pulled a 9-millimeter handgun from his waistband and shot at a vehicle five times after the driver of the car pulled a silver handgun on him. One of the bullets Elkins shot was found near a school where children were playing outside, the Times said.Like Blaze News?
