Incident

Brian C. Mulkeen captained the track and field team at Fordham University and graduated from its Gabelli School of Business with a bachelor's degree in 2008. He worked as a financial adviser at Merrill Lynch in New York before leaving to pursue a career in public service. He joined the New York City Police Department on 9 January 2013, was first assigned to the 48th Precinct and later transferred to Patrol Borough Bronx. In about six years he made approximately 270 arrests, many for serious gun offenses, and earned five medals for police excellence. Standing six feet four inches tall, he was known as cheerful and helpful, and he loved to play guitar and sing, even for crowds of strangers.

On 29 September 2019, Police Officer Mulkeen was working with a plainclothes anti-crime unit targeting drug gang activity, including a recent shooting, at the Edenwald Houses in the Bronx. Officers saw a suspicious man behind one of the buildings, and when three of them got out of their car to question him, he ran. At about 12:30 a.m., Officer Mulkeen chased the man, 27-year-old Antonio Williams, who was armed. He caught him, and as they struggled on the ground he saw Williams reach for his gun, shouted a warning to the officers arriving behind him, drew his own weapon and fired five shots. The responding plainclothes officers also opened fire, and Officer Mulkeen was struck in the head and torso by their bullets. He was taken to Jacobi Medical Center, where he died. Williams was also shot and killed.

Brian Mulkeen was 33 years old. He was survived by his parents, his sister, his brother and his girlfriend, a Bronx police officer. At his funeral on 4 October 2019, Police Commissioner James P. O'Neill posthumously promoted him to detective first grade with shield number 9004. On 1 July 2021 the Monroe Police Department dedicated a German shepherd K-9, "Keen," in his honor, and on 27 July 2021 the NYPD also dedicated a K-9 to him.
