A killer awaits sentencing after pleading guilty to three brutal murders within the span of two weeks last spring.

John Paul Ostamas,40, faces an automatic life sentence, with parole eligibility of between 10 and 25 years to be decided during sentencing.

"I'm positive that what he did will not be neglected," said Ron Monias, the father of one of Ostamas' victims.

Hours after Ostamas pleaded guilty in court, he spoke to CTV News inside the Winnipeg Remand Centre.

Handcuffed and wearing a grey sweat suit, Ostamas appeared calm and said he’s at peace with the fact he may spend the rest of his life in prison.

“It doesn’t worry me at all,” Ostamas told CTV News. “I grew up in a harsh life, so that doesn’t really bother me.”

“It’d be a tough case to fight, that’s why I pleaded guilty, because of the surveillance. That was my only option just to plead guilty, get it dealt with and move on.”

Ostamas declined to talk about the specifics of his crimes, but court records lay out the chilling facts of the killing spree he went on in April 2015.

According to the agreed statement of facts in the case, Ostamas was a stranger to each of his three murder victims.

In the early morning hours of April 10, 2015, Ostamas came across his first victim, Myles Monias, sleeping in a downtown bus shelter at Main St. and Pioneer Ave.

Ostamas stomped on Monias’ head, and then left him on the ground and took off.

Monias was discovered by Winnipeg Transit workers later that morning, and was taken to hospital in critical condition where he died of his injuries.

An autopsy determined the cause of death to be blunt force trauma.

After the murder, Ostamas dumped Monias’ bloody clothes in the Red River from the Queen Elizabeth Bridge.

Two weeks after killing Monias, surveillance video captured Ostamas and his second victim, Stony Bushie, together near Hargrave St. and Ellice Ave. in the early evening hours of April 24.

A witness saw Ostamas trying to grab Bushie’s arm before the two walked away together.

Surveillance footage outside the APTN captured footage of the killing itself.

Ostamas threw Bushie to the ground, grabbed a two-by-four piece of lumber from a nearby construction trailer which he used to hit Bushie in the head, breaking the piece of wood upon impact.

Ostamas continued to unleash a violent attack, and then dragged Bushie’s body behind a pile of plywood sheets, where he removed his clothing.

Surveillance video shows Ostamas leaving the scene with Bushie’s clothing, which he dumped into a river.

Two hours after killing Bushie, witnesses saw Ostamas approach his third victim, Donald Collins, at Ellice and Hargrave.

Surveillance video showed Ostamas leaving the area with Collins.

Collins’ body was discovered by a pizza delivery driver, underneath garbage bags and clothing behind a dumpster in a downtown back lane later that same night.

An autopsy determined Collins died of blunt force and sharp force injuries.

Ostamas told police he took Collins to a parking lot, where he stomped his head and face. He also admitted to throwing Collins’ clothes in the river.

Months after his arrest, Ostamas met with his spiritual care giver in October 2015 at the Remand Centre.

He told the care giver his pregnant girlfriend had been sexually assaulted by four individuals, and that he was very angry because her unborn child had died.

He later told a Remand Centre counsellor he killed the three men as a means of revenge.

Ostamas told the counsellor, “It would have been four (men), but I only found three.”

A police investigation found no record of his pregnant girlfriend.

When asked by CTV News about the woman, Ostamas declined to comment.

Sentencing is set for June 27.
