Two suspects are in custody after a police officer was shot and killed in Landover, Maryland.

Twenty-eight-year-old Jacai Colson, a four-year veteran of the Prince George's County Police Department, died of his injuries at Prince George's Hospital Center on Sunday evening.

"He was a police officer who was a real cop's cop. He didn't shy away from any calls. He never shirked his responsibility. He was always working, and he was always there for his brothers and sisters," the president of the Fraternal Order of Police told reporters.
