DALLAS — A Little Elm, Texas, police officer was shot and killed Tuesday afternoon after police approached a man carrying a gun in a residential area, according to authorities. The suspected shooter was later killed after an hours-long standoff.

The suspected gunman was found dead around 10 p.m, The Dallas Morning News reported. He had holed up in a house in the 1400 block of Turtle Cove Tuesday evening, surrounded by police and SWAT. A Twitter account for the City of Little Elm called it an "active shooter situation in the area of Lobo and Eldorado."

Officers responded to the home around 3 p.m. CT after residents reported seeing a man with a gun, officials said. After being told to drop the weapon, the suspect began shooting at officers from inside the house, Lt. Orlando Hinojosa said. Detective Jerry Walker was hit, officials said at a news conference.

Other officers were able to drive a squad car to Walker's aid and move him to another area where he was airlifted to the Denton Regional Medical Center, where he later died.

No other injuries were reported.

Walker, 48, was a father of four and an 18-year veteran of the force, said Rodney Harrison, Little Elm chief of police. Walker was promoted to detective in 2013.

Police poured into the residential area in the far-north Dallas suburb, causing school bus delays at multiple nearby Little Elm schools. The Little Elm Independent School District released a statement saying some students who walk home were being held at school until parents could come get them.
