Bridgeport police have identified a suspect in Thursday's fatal shooting of a 23-year-old woman, and are asking for the public's help in locating him.

Police say they've obtained an arrest warrant for Derrick Francis, 41, who's accused of killing Brianna McKoy, 23, in a domestic violence incident.

Police say Francis is considered armed and dangerous.

Francis is described as 5 feet 8 inches tall and 170 pounds with black hair and brown eyes. Police say he's known to frequent the North End of Bridgeport and the Bronx.

Police responded to Coachlight Square Condominiums on Vincellette Street around 11:30 Thursday morning. Police found McKoy unresponsive and say she'd been shot to death. They continue to investigate the circumstances surrounding her death.

This is the second fatal shooting in Bridgeport this week.

Police say Deron Dacosta, 21, was shot and killed at the Trumbull Gardens housing complex just before 11:30 Tuesday night. No arrests have been made. Police say they're working several leads.

The two incidents mark the city's fifth and sixth homicides of the year.
