Guelph Police say they have no suspects and are asking the public for help as they continue to investigate the hit-and-run crash that killed 24-year-old Grace Glofcheskie.

Meanwhile, Ontario’s Special Investigations Unit is running its own investigation into the interaction between the driver of the SUV that hit Glofcheskie and police officers at a nearby RIDE checkpoint.

The SUV was allegedly fleeing the checkpoint when it somehow became airborne and crashed into a hydro pole.

In the aftermath of the collision, the pole was severed, the vehicle was on its roof, and Glofcheskie – who had walked a friend home and was returning to her own house – was badly injured.

The 24-year-old was taken to hospital, where she was pronounced dead.

The RIDE checkpoint had been set up to the east, at Rose and Arthur streets. The crash occurred near the intersection of Woolwich and Charles streets.

When officers responded to the crash site, whoever had been inside the SUV was nowhere to be found.

“We still do not have any suspects. The occupant or occupants are unknown,” Const. Mike Gatto told a press conference Monday morning.

“If you know anything about this incident, we’re encouraging you to contact the Guelph Police.”

The severity of the collision leads police to believe that whoever was in the SUV may have been injured in the crash.

Chief Jeff DeRuyter said the case is being considered the “highest priority” within the Guelph Police Service.

Fifteen investigators are working on the case, examining the SUV – a 2007 Ford Escape which had been reported stolen from an east-end property a few hours earlier – and interviewing people who were in the area at the time.

“There’s not a stone we’re going to leave unturned,” Gatto said.

“This one bothers us. It bothers us a lot.”

DeRuyter urged whoever was behind the wheel of the SUV to “do the right thing” and turn themselves in.

“The investigation will not end until the responsible party or parties have been identified and held accountable for their actions,” he said.

A small memorial to Glofcheskie was started Monday morning, and continued to grow through the day.

Guelph resident Jim Donovan was the first person to drop off a flower at the crash night, saying that he and his family wanted to express sympathy after the “senseless tragedy,” even though none of them knew Glofcheskie.

“It’s just something that should never have happened,” he said.

Glofcheskie had been studying human kinetics and biomechanics at the University of Guelph, and had recently received her master’s degree.

“She was very involved with the department – a really engaged student,” said Brenda Whiteside, the school’s associate vice-president of student affairs.

She was also a past captain of the school’s golf team, and had been working with her former teammates this fall despite not being on the team herself.

After the holidays, Glofcheskie was planning on moving to Florida, where she had landed an internship at a sports facility.
