About a month before a shooting injured three people at a downtown St. Paul pool party, the suspect and one of the victims had been in a physical fight, according to attempted murder charges filed this week.

The triple shooting happened about 11:45 p.m. June 20. Officers responded to the rooftop pool at Kellogg Square apartments at Kellogg Boulevard and Robert Street.

One of the men charged in connection to the case was also accused this week in a shooting on June 1 at Minneapolis’ Boom Island that killed a woman and injured five other people.

In the St. Paul case, surveillance video showed two men arrived to the party wearing masks and purple latex gloves.

The 23-year-old man who’d been in the previous fight “confronted the two masked men,” according to the criminal complaints. He punched a man wearing a brown hoodie, causing him to stumble backward. The man in the hoodie pulled out a gun, and the 23-year-old also pulled “what appeared to be a firearm.”

The man in the brown hoodie fired his gun toward the 23-year-old and two other people, the complaints said. The 23-year-old did not appear to fire.

Another man, later identified as Marquez Demar Hill-Turnipseed, ran toward the confrontation while reaching into his hoodie. He pulled out a gun and fired several shots toward the masked men, the complaints said.

The 23-year-old later arrived at Regions Hospital with a gunshot wound to his knee. Police found that man’s twin brother at the apartment building with a gunshot wound that entered his upper pelvis area and a 16-year-old who’d been shot in the ankle. They were both taken to the hospital by ambulance with non-life threatening injuries.

Police located nine spent casings in the area where the man in the hoodie fired, and three spent casings in the area from where Hill-Turnipseed fired, the complaints said.

Video surveillance

Surveillance footage showed the masked men were dropped off near the building around 11:40 p.m. by what appeared to be a ride-share vehicle. Through investigation, police determined the ride was booked by an Uber account belonging to “Tyson Bands” and the phone number belonged to 19-year-old Tyson Joseph Volk, the complaints said.

Police carried out a search warrant on the phone of the 23-year-old who initially confronted the men and it showed he and Volk in a fight about a month before the shootings, the complaints said. In the video, the man yelled at Volk, “You told me I better have a gun when you see me,” the complaints said.

The 23-year-old also had two phone numbers for Volk in his phone.

Police arrested Volk, of St. Paul, Friday morning and arrested Hill-Turnipseed, 23, also of St. Paul, last week in Chicago. It wasn’t clear Friday whether either man is represented by an attorney.

The Ramsey County Attorney’s Office charged Volk with three counts of attempted intentional second-degree murder, not premediated, and three counts of second-degree assault with a dangerous weapon.

Hill-Turnipseed is charged with possession of a firearm by a person who was ineligible due to a conviction of a crime of violence.

Other cases

The Hennepin County Attorney’s Office charged Hill-Turnipseed on Wednesday with aiding and abetting murder and other counts in the Boom Island shooting, in which 23-year-old Stageina Whiting was killed.

Hill-Turnipseed isn’t eligible to possess a gun because he is on federal supervision for illegal possession of a machine gun in a 2023 federal case. He also was convicted in Hennepin County of possession of a machine gun.

In a separate and ongoing court case, Volk has been out on bond since February 2024. The Ramsey County Attorney’s Office charged him with aiding and abetting first-degree aggravated robbery of a man, now 20, who said he went to Weida Park in St. Paul to smoke marijuana with two acquaintances when he was hit with a handgun and robbed.
