As a wounded Milwaukee police detective remained hospitalized Friday, more details emerged about the teenage suspects police believe were involved in the shooting.

Two suspects, one 19 and the other 18, were free on bail in other felony cases prior to the shooting.

The incident began as an attempted carjacking and evolved into an attempted robbery involving the same victim. The attempted robbery occurred inside a Shake Shack restaurant and the off-duty detective exchanged fire with the suspects. The detective was wounded in the gunfight and the suspects fled.

The wounded 37-year-old detective, who has seven years of experience, was in stable condition Friday, Milwaukee police told the Journal-Sentinel.
