Two people opened fire during a gathering at a St. Paul home over the weekend, leaving a woman and one of the suspected shooters injured, police said Monday.

Officers were called to a Payne-Phalen residence on Saturday about 3:40 a.m. after receiving reports from multiple people who said they heard shots from different types of guns, according to a search warrant affidavit.

A woman also called from the home in the 600 block of East Orange Avenue and said she had been shot twice. Police found the 22-year-old woman at Edgerton Street and Orange Avenue with a gunshot wound to her lower leg, according to Sgt. Mike Ernster, a St. Paul police spokesman.

Officers went to check the home and found “multiple bullet casings and blood trails” inside, according to the affidavit. One trail led to a home in the 1200 block of Edgerton Street, southwest of the Orange Avenue address.

Police who followed the trail found an empty revolver, with blood on it, under a parked car. They discovered a 38-year-old man, shot five times, in front of a residence. The blood trail also led to the back of the address, where officers found two bloody gloves, the affidavit said.

Paramedics took the injured man and woman to the hospital. Their injuries were not considered life-threatening, Ernster said.

Witnesses said a group of friends were at a St. Paul bar earlier in the evening and went to the Orange Avenue home for an “afterparty,” according to the affidavit. At one point, a man and some of the partygoers got into an argument in the front yard. People overheard the man saying he was going to get his gun and come back.

The man left in a cream-colored Cadillac Escalade, returned about five minute later, pushed in the side door of the residence and started shooting, according to the affidavit. He then fled.

Police found a cream-colored Escalade one block south of the crime scene. The vehicle is registered to the injured man, according to the affidavit.

The search warrant, which a judge granted, was for the home where the shooting occurred. Police found 16 9mm casings and 10 .45-caliber casings, along with other evidence, according to an inventory receipt.

No had been arrested as of Monday afternoon.
