Officer Nicholas Sloan was shot and killed while conducting a narcotics operation on North Taylor Avenue.

Officer Sloan and his partner were participating in a narcotics operation made possible through the federal Weed and Seed Program. The officers were observing drug sales in the parking lot of a liquor store. Upon observing a transaction, he and his partner approached one of the subjects. The man immediately began to struggle with the officers. During the struggle Officer Sloan suffered several injuries, including a deep gash above his right eye.

As the three continued to struggle the suspect was able to gain control of Officer Sloan's service weapon. He shot Officer Sloan once in the chest, just above his vest. The suspect then fired at Officer Sloan's partner three times, striking him twice. Despite being wounded, the partner was able to return fire and killed the suspect.

Officer Sloan had served with the St. Louis Police Department for just over 2 years. He is survived by his 13-month-old child, girlfriend, parents, and two sisters. His father serves as a sergeant with the St. Louis Police Department's Vice/Narcotics Division.
