WASHINGTON — The trial of a man accused of shooting and killing a Prince George’s County, Maryland teacher and their 2-year-old daughter begins with jury selection Monday.

Daron Boswell-Johnson was 25 when he allegedly shot and killed NeShante Davis and their daughter, Chloe Davis-Green, in February 2016, said prosecutors, who added in a statement that Boswell-Johnson has admitted to the killings.

The prosecutors said that in November 2015, a paternity test determined that Boswell-Johnson was Chloe’s father, and he was ordered to pay $600 a month in child support. Boswell-Johnson drove to Davis’ home in Fort Washington, Maryland, Feb. 2, 2016, and waited for her to come out.

When she did, and while she was putting Chloe in a child seat, Boswell-Johnson came up to her and demanded she drop the order, prosecutors said.

He then shot both of them and fled, prosecutors said.

Detectives found Johnson later that day at his job in Gaithersburg, and he agreed to go to police headquarters for an interview. He admitted to the killings there, the prosecutors said.

Davis was in her first year as a teacher at Bradbury Heights Elementary School.

Boswell-Johnson is charged with two counts of first-degree murder and two counts of use of a firearm in a crime of violence. Prince George’s County State’s Attorney Angela Alsobrooks will prosecute the case herself — the second time she’s done so, her office said in the statement.
