ST. LOUIS • Three men were shot in a little more than 90 minutes overnight Sunday and early Monday, St. Louis police said.

Police responded to a call of a "prowler attempting entry" and then a shooting call at 11:30 p.m. Sunday in the 4600 block of South Compton Avenue. Officers found a 21-year-old man suffering from a gunshot wound to his leg.

Upon investigation, police learned that the 21-year-old man was attempting to enter a woman's house when a 20-year-old man shot at him. The shooter then fled from the house.

The injured man was taken to an area hospital where he was listed as stable. The shooter eventually returned to the scene and told police he had dropped the gun as he ran.

Fifteen minutes later, police got called to another shooting, this time at 14th and Spruce streets downtown. The intersection is near the Civic Center MetroLink stop.

The victim was taken to a hospital by private car. He was listed in critical condition but stable. Two 25-year-old men were taken into custody with help from MetroLink security, police said.
