Three teenagers are facing legal charges connected to what Wisconsin police are calling a “wild west-style shootout” that resulted in the deaths of a hopeful nurse and a teenage boy at a strip mall party.

Earl Williams III, 17, is charged with felony murder, attempted first-degree intentional homicide, and having a machine gun. Jardan Anderson, 18, and Isiah Daniels, 17, are each charged with harboring or aiding a felon.

The shooting took place on June 20 in Milwaukee, with authorities recently unveiling a criminal complaint that portrays the frenzied gunfight, during which 110 rounds were fired from 11 guns in just 20 seconds, according to a probable cause arrest affidavit reported by Law&Crime.

Police were called around 11 p.m. to 8223 W. Brown Deer Rd. for reports of shots fired. Officers arrived to find 19-year-old Bre’nee Veasley with a gunshot wound to her abdomen. Emergency services attempted life-saving measures but later declared her deceased. Another victim, 17-year-old Kingston Liphford, was also killed, and three more individuals aged 14, 15, and 17 sustained gunshot injuries, according to officials.

Investigations revealed gunfire was concentrated in three separate zones, supporting the description of a “wild west-style shootout,” police indicated. Footage from surveillance cameras revealed the initial shots originated from an automatic weapon.

A partygoer accompanying Veasley mentioned they entered the building for roughly 20 minutes before stepping back out to the parking lot, where Daniels was near a Chevrolet Malibu. She was talking to him when she noticed a masked man brandishing a gun.

The witness told investigators she asked the man to put the gun away because it was “scaring her.” Moments later, the masked person allegedly opened fire starting the shootout. The witness reportedly ducked under some cars and later saw Veasley had been shot.

Detectives spoke with Daniels who said he arrived at the party with Williams and Anderson in the Malibu. Daniels allegedly said Williams had a gun with a switch on it that makes a semi-automatic firearm automatic. Anderson also spoke to detectives and stated they drove Williams away from the scene and then spray painted the Malibu “in order to attempt to avoid detection related to this shooting,” cops wrote. Williams allegedly told his co-defendants he started shooting because he believed there were rival gang members with guns in the parking lot.

Some 17 days after the shooting, cops responded to a weapons call. A Nissan Maxima crashed into a police car and all the people inside got out and ran. The front passenger, Williams, was allegedly in possession of a Glock 23 with a switch on it. There were 13 shots fired from that weapon in the strip mall party shootout, cops said.

While cops do not believe Williams fired the shots that killed Veasley, they allege he caused the death by opening fire starting the shootout. Williams remains in the Milwaukee County Jail on a $300,000 bond, while it appears Daniels and Anderson have since bonded out.

According to a GoFundMe account, Veasley was going to college to become a nurse.

“A 19-year-old with her whole life ahead of her. A college student. A nurse, taken the night before her first day saving lives. A peacemaker. A light in our family,” the fundraiser said. “A 4.0 GPA her entire scholastic career. She did everything right—and still, this city failed to protect her. Bre wasn’t in the streets. She wasn’t in trouble. She was simply trying to enjoy her time out of school at a teen party. But because of fragile egos, poor conflict resolution, and unchecked violence, she never made it home.”

Williams has a court date scheduled for Monday, while Anderson is slated to appear on Sept. 29. Daniels’ next court appearance is unclear.
