Who is John Paul Ostamas, alleged serial killer in Winnipeg deaths?

Details are emergingabout John PaulOstamas, the 39-year-old homeless man accused of killing three other men in downtown Winnipeg,based on information from police, people who have met him and evenhis own Facebook page, in which he wrote "somebodys [sic] gotta die" on the day two of the men were found dead.

The post, which appears publicly on one of hisFacebook pagesas of Tuesday afternoon, was attached to a YouTube link he posted of a music video for Somebody's Gotta Die by Biggie Smalls, also known as the Notorious B.I.G.

Ostamas also wrote, "Yea though I walk through the valley of the shadow of death I will not fear" next to a YouTube link for You're Nobody ('Til Somebody Kills You) by the same hip-hop artist.

The linkswere among six Biggie Smalls music videos that were posted on Ostamas'spage that day, along witha link to the video for When I'm Gone by Eminem.

April 25 was when the bodies of Donald Collins, 65, and Stony Bushie, 48, were discovered in back alleys near Hargrave Street and Portage Avenue.

The victims had been attacked and left for dead, according to Winnipeg police, who called both incidents "brutal killings."

Ostamas has been charged with two counts of first-degree murder in the deaths of Bushie and Collins and one count of second-degree murder in the death of Miles Monias, 37, who died after he was found beaten inside a bus shelter at Main Street and Pioneer Avenue on April 10.

'He seemed like a nice guy'

One of the last people to see Ostamas before he was arrested was Brenda Sinclair, who said she was about to rent one of her rooms to him.

"Yesterday morning, I sat and had coffee with him," Sinclair said Tuesday."He seemed like a nice guy."

Sinclair said police visited her later on Monday to ask about Ostamas, and she demanded to know what he is accused of doing.

"'What did he do?' I said, because I need to know this man was about to live with me!"she exclaimed.

Sinclair said she was shocked upon learning thatOstamas faces three murder charges. She addedthat she cannot believe how close she came to living with a suspected killer.

Had a violent record in Thunder Bay area

Winnipeg police Supt. Danny Smyth said officers had little contact with Ostamas before he was arrested on Monday in connection with an unrelated assault.

Police later learned that Ostamas's record includes a domestic assault in March, he added.

Smyth noted that Ostamas does have a criminal record in northwestern Ontario, where he is from.

"Ostamas has a violent record for multiple assaults in the Thunder Bay area dating back to 2002," he told reporters on Tuesday.

"Our investigators will be contacting police in other jurisdictions where Ostamas is known to have travelled."

In an email, anOntario Provincial Police spokesperson told CBC News there are "no outstanding charges laid by the OPP" against Ostamas as far as officials can determine.

Charlie Okeese, a band councillor from Eabametoong First Nation, or Fort Hope First Nation, in northwestern Ontario confirmed to CBC News that John Paul Ostamas is a band member there.

'He's in a lot of trouble,' says lawyer

Smyth said Ostamas has been in Winnipeg off and on for the past 10 years and stayed at a number of homeless shelters.

Greg Brodsky, the accused's lawyer, says Ostamas has no fixed address spent a lot of time on the street.

"He needs some legal help," Brodsky said. "He's in a lot of trouble."

Brodsky said his client lived in Fort Hope until he was seven years old, then moved around.

At least four Facebook pages are under Ostamas's name, two of which use the name Jonathan Ostamas. All show similar photos of him. One of the accounts was active until April 26, one day before he was located by police.

Along with the music video posts, Ostamas wrote on April 25 about being "in Canada again chillin like a mutha fa" and going back to the United States.

He also harboured adistrust of police. On April 16, Ostamas wrote a Facebook post alleging that police in the Fort Hope area tried to kill him when he was a child.

He wrote that the legal system "did me wrong and violated my rights" and called the RCMP and police "the worst criminals on earth."

'Just don't call the cops,' Facebook post reads

A different post on April 17 included comments like "I be mobbing and doing things like always hit them up!" and "Just don't call the cops."

The last post on hisFacebook page, dated Sunday evening, simplyread, "The crime familia."

On Tuesday, Brodsky said Ostamas was in a "somewhat distressed mode because of the nature of the charges against him," but he had yet to speak with his client since the charges were laid.

"I have to talk to him again as soon as he gets here [the Remand Centre]," Brodsky said.

"Then I want to talk to the police to find out the basis on which these charges were laid and then I want to appear for him in court, which I expect to be tomorrow."

Brodsky declined to say what Ostamas had been doing in the city or whether Ostamas knew the men he is accused of killing.
