Chicago police officers are mourning after one of their own was killed in the line of duty Wednesday.

Officer Andres Vasquez-Lasso, 32, was shot and killed as he chased a teenaged armed suspect who suddenly turned and fired "at close range" in Gage Park, FOX 32 reports.

The incident began to unfold around 4:45 p.m. when two police cars responded to a domestic-related call in the 5200 block of South Spaulding Avenue. A caller said a suspect was chasing a female with a gun, Police Superintendent David O. Brown told reporters. 

When officers arrived, one officer knocked on the door of where the call originated. A second officer engaged with the suspect and a chase ensued where gunfire was exchanged.

Vasquez-Lasso engaged in the chase exchanged gunfire with the offender at close range. The suspect, reportedly 18 years old with one prior criminal violation, was shot in the head and taken to an area hospital in critical condition.

Vasquez-Lasso was struck multiple times and was taken to Mount Sinai Hospital.

"Vasquez-Lasso had been on the force for five years, and Brown said he had a very bright future ahead of him. Brown also noted that the officer comes from a family of public servants," FOX 32 stated.
