Portland police continue to investigate the death of 23-year-old activist Sean D. Kealiher, who died Saturday after being hit by an SUV.

Meanwhile, on Sunday, Kealiher’s community of family, friends and activists were grieving.

Police have released few details about the circumstances of his death. The medical examiner’s report shows Kealiher was killed by blunt-force trauma. Homicide detectives are investigating.

Multiple sources told the Oregonian/Oregonlive that Kealiher was run down by an SUV just after midnight Saturday after leaving Cider Riot, a popular Portland cidery and left-wing watering hole. He was hit outside of the Democratic Party of Oregon building on Ninth Avenue, where a bloodstain could still be seen Saturday afternoon. Friends brought him to a hospital, where he died.

Police arrived at the scene responding to a call of gunfire and found an abandoned SUV crashed into the DPO building, with evidence of gunfire into the vehicle. Police have not released any information about the status, whereabouts or identity of the SUV’s driver.

The case has set off a stream of wild rumors on social media, none of which have been confirmed.

“We ask our community members to limit their speculation and allow the detectives time to do their important work," Portland police spokesman Kevin Allen said. “We will release further information if it can be done without compromising the investigation.”

Kealiher was a self-described anarchist and a leader in a tight-knit community of grassroots activists. Teressa Raiford, a friend of Kealiher’s and a Portland activist, described him as a dedicated social justice community organizer, educator and ally who was outspoken against racism, discrimination and inequality.

“He did a lot of the work we should all be doing,” Raiford said. “He was too young to be killed and to die in Portland.”

Kealiher, who was also known in the activist community as Anteo/Armeanio, was an activist for most of his life, Raiford said, always willing to pour his energy toward social justice; a young man bearing the burdens of social issues.

“I wish we had more of his time, energy and love. My heart is broken for his mother and for our entire community,” Raiford said.

Friends set up a memorial for Kealiher on Saturday, placing candles and flowers around the spot where he was hit.

“At the first protest I ever held a young anarchist came up to me and offered to be my security,” tweeted friend Gregory McKelvey. “He stuck by my side for a week, never leaving the protest.” McKelvey was a co-founder of Portland’s Resistance, an activist group that sprang up immediately following President Donald Trump’s election in 2016.

Kristy Hathaway, who said she was Kealiher’s recent ex-girlfriend, wrote about him on social media platforms Saturday.

“I told him all the time that he was my hero,” Hathaway wrote. “Of course he rolled his eyes at that, but it was true. I love you, Sean. Your loss is felt deeply all over the world.”

Friends also set up a GoFundMe account to raise $5,000 for Kealiher’s family to pay for funeral expenses. Since it went live at 1 a.m. Sunday, the account has raise more than $7,000.
