St. Paul police were investigating a fatal shooting Saturday outside a University Avenue dive bar, even as they made an arrest in another shooting death Friday in the city's North End.

Saturday's shooting was in the 900 block of W. University Avenue, between Lexington Avenue and Victoria Street, police said. Officers were called about 2 a.m. and arrived to find a man with an apparent gunshot wound outside Johnny Baby's bar. He died at the scene.

Only one person at the scene agreed to speak with officers, police said. Investigators are asking anyone who was there or who knows what happened to call the homicide unit at 651-266-5650.

"This senseless violence affects the entire city, and we need your help," police said in a tweet.

Authorities have recorded 358 calls for service at Johnny Baby's in the last year — an unusually high number that includes 220 "proactive" visits, said police spokesman Mike Ernster.

In Friday's shooting death, a 28-year-old St. Paul man was booked into the Ramsey County jail early Saturday on suspicion of murder, police said. The suspect has three previous felony convictions for domestic assault and one for illegal possession of ammunition or a firearm.

The victim, who has not been identified, was in a parking lot about 12:15 p.m. Friday at the corner of Arundel Street and W. Maryland Avenue when several bullets were fired into his car, police said. The man died at the scene.

The two deaths marked St. Paul's eighth and ninth homicides of the year.

Meanwhile, in Minneapolis, police continued to look for a suspect in the fatal shooting of a man early Friday in the downtown Warehouse District.

Preliminary information indicated that a disturbance between two groups of people escalated into gunfire and the victim was struck, according to police spokesman John Elder.

Shots rang out about 12:20 a.m. on the 300 block of N. 1st Avenue. Police arrived to find a good Samaritan aiding the victim, who died later at HCMC. The name of the victim has not been released.
