Police are asking the public to help them identify whoever shot and killed a St. Paul man in Inver Grove Heights on Saturday morning.

Billy Ray Robles, 19, was killed when a dispute on a “party bus” broke out into a fight that escalated to a shooting. He was transported to Regions Hospital in St. Paul, where he was pronounced dead from a gunshot wound.

Officers responded to a call about 1:30 a.m. at the AMC Showplace 16 on Bishop Avenue, where they found a “chaotic” scene with 40 to 50 people in the parking lot. The party bus was there dropping off revelers who had left their cars at the theater between 10 and 11 Friday night.

A fight had broken out between two groups of men on the party bus. The motive for the fight and shooting had not been determined, Inver Grove Heights Police Chief Paul Schnell said Saturday.

As officers from nine law enforcement agencies worked to secure the scene and search for suspects, they found Robles unresponsive and another man with facial injuries. Related Articles Minneapolis boy charged in shooting death of campaign worker

Police stopped a vehicle that had left the scene and was traveling at a high rate of speed north on U.S. 52. A juvenile male with a non-life-threatening gunshot wound to his leg was inside the car. He was taken by ambulance to Regions Hospital.

Family members say Robles was a good guy trying to do the right thing when he was shot.

“He was trying to break up the fight,” said Darleen Tareeq, Robles’ cousin. She started a GoFundMe page for the family to help with funeral expenses. She was not on the party bus, but had been told details from other family members, she said.

“His grandma texted me at 3 in the morning and said somebody shot Billy and he’s dead,” Tareeq said. “He’s got nine brothers and sisters, so a lot of people are hurting right now.”

Tareeq said Robles loved to rap and had posted a few videos to YouTube.

“He was really passionate about it,” she said. “He was really good at it.”

She did not know why he was on the party bus, but believes he was trying to stop the fight.

“He’s always the caretaker because he’s got all those brothers and sisters. That’s the kind of person he was,” she said.

Robles played football and baseball for Humboldt High School in St. Paul.

Tareeq thought it was sadly ironic that her young cousin was shot on the day of nationwide youth-led marches against gun violence.

“Today people marched against gun violence and my baby cousin lost his life to gun violence,” she said. “We were not prepared to bury one of our children.”

Despite a comprehensive search of the shooting scene, which included a K-9 unit and the Minnesota State Patrol helicopter, the suspect or suspects were not found, police said.

Anyone with information is asked to call the Inver Grove heights Police Department at 651-450-2525.
