A 22-year-old man who collapsed on Brighton Avenue after crashing his car Saturday afternoon died of a stab wound to the chest, Portland police said Monday.

A candlelight memorial for Patrick Lobor, who was 22, is scheduled for 7 p.m. Tuesday at the Munjoy South basketball courts.

Patrick Lobor, a former Deering High School basketball player, was driving one of three vehicles involved in a crash Saturday afternoon on Brighton Avenue. Police said Lobor got out of his car, stumbled to the middle of the intersection and collapsed. He was found dead by first responders.

Lt. Robert Martin said Monday in a news release that police are confident there was no crime, but he would not say how Lobor ended up being stabbed.

The manner of death – such as homicide, suicide or accident – remains under investigation and police are still looking to speak with anyone who saw the crash or had contact with Lobor before the incident, Martin said.

Mark Belserene of the state Medical Examiner’s Office said Monday that an autopsy on Lobor had been completed but the case is “pending further studies.”

Lobor was the only occupant of a silver 2004 Toyota Corolla traveling on Riverside Street toward Brighton Avenue when it struck a blue 2007 Chevrolet Cobalt that was stopped at a traffic light. The driver of the Cobalt, Ashley Hallstrom, 32, and her passenger, Eric Kingston, 40, both of Gorham, were taken by ambulance to the hospital, where they were treated and released. Hallstrom’s car was forced into the side of a Chevy Equinox driven by Matthew Foster, 22, of Casco. Foster was not injured, police said.

More than a dozen family members and friends gathered Monday afternoon inside the Munjoy Hill home of Lobor’s parents – Robert Lobor and Christina Marring. The family are Sudanese refugees who came to Portland in 2004.

A Portland police officer interrupted the gathering around 4 p.m. and took two family members aside to have a private conversation.

“We’re in no shape to talk to anyone now,” Lobor’s sister, Lily Lobor, said after meeting with the police officer.

Patrick’s brother, Richard Lobor, was shot in the head and died at age 23 on Nov. 21, 2014, at an apartment at 214 Brighton Ave. His murderer, Abdirahman Hussein Haji-Hassan, was arrested and convicted.

On Monday, Lily Lobor shared a link on her Facebook page to a GoFundMe campaign aimed at raising $10,000 to pay for burial expenses. The campaign, which was created by Lyd Ismail, had raised more than $5,000 by Monday evening.

In the GoFundMe post, Ismail wrote about Lobor’s life and accomplishments.

“Patrick was not only an impeccable basketball player, but a leader in his own right. His compassion and honesty touched every individual that he has come across and now has transcended after him,” Ismail said.

Ismail said Lobor grew up in Portland and became involved in the community at a young age. He spent time at the Boys & Girls Club and played basketball on the Kennedy Park basketball courts before showcasing his athletic skills on the big stage at the former Cumberland County Civic Center.

At 6 feet 5 inches tall, Lobor was a multisport athlete at Deering High School, where he helped lead his basketball team to a state championship in 2012.

He went on to play basketball at Southern Maine Community College during the 2016-2017 season. He studied health sciences at SMCC and worked at a South Portland hotel.

“He was known to many as shy and quiet, but to the individuals that were blessed enough to be in his presence, they were met with a lively personality and a sense of humor that was unmatched,” Ismail wrote. “The Patrick we all know and love has instilled principles in each and every one of us to be the best that we can.”

Ismail noted that after the death of his brother in 2014, Patrick took on greater family responsibilities.

“After this loss to the family, Patrick assumed the role of the eldest brother. Looking out for each of his siblings and making sure they were better than how he left them. This showed his constant selflessness and courage,” Ismail wrote.

Lobor’s father, Robert Lobor, on Sunday described his son as a “good boy, very decent, very quiet” who taught his two younger brothers how to play basketball.

In a post Monday on Facebook, friends and family said they plan to hold a candlelight memorial vigil for Patrick Lobor on Tuesday evening at the Munjoy South basketball courts, 27 Mountfort St. The vigil will begin at 7 p.m.
