A former Portland bartender with what authorities describe as a 'violent obsession' with the athletics club that fired him allegedly turned a rental SUV into a rolling bomb. Investigators say the driver, identified by family as 45-year-old Bruce Whitman, had packed the vehicle with explosive materials, including propane tanks and pipe bombs, before smashing through the front doors of the Multnomah Athletic Club. The impact triggered a fiery blast that killed him and left the building's lobby in ruins.
The Attack
The shocking early-morning attack unfolded just before 3 a.m. on Saturday in the city's Goose Hollow neighborhood. Security footage captured the terrifying moment a dark SUV barreled into the club, shattering glass and tearing across the ground floor. Some of the devices detonated, igniting a blaze that tore through the entrance area and caused millions of dollars in damage as it spread further inside the gym. Despite the scale of the destruction, no one else was injured. Authorities believe Whitman rented a black Nissan Rogue the day before the attack and used it to ram into the building before setting off the explosives.
Investigators believe the explosives included a combination of propane tanks and pipe bombs, though not all devices detonated. The blast caused extensive damage to the ground floor, with officials describing the lobby as heavily destroyed. The impact alone sent debris flying through the lobby, but it was the subsequent blast that turned the scene into what one source described as 'complete devastation.'
Aftermath and Investigation
Explosive Disposal Unit crews later recovered evidence of explosive materials from the wreckage, while firefighters battled flames that spread through the club's lower level. The driver was found dead inside the vehicle. Police initially withheld his identity, but his mother, Rita Lenzer, confirmed to reporters that Whitman was responsible after being contacted by detectives. 'And then I didn't hear from him,' Lenzer said of their final communication the day before the attack. 'Until I got a call from the detective the next morning.'
Background of the Suspect
Whitman had previously worked as a bartender at the exclusive club but was fired. That event appeared to mark the start of a troubling downward spiral. Court documents show he later turned up at the homes of club members and made threats, while also being spotted repeatedly outside the facility confronting people connected to it. Lenzer acknowledged her son's fixation. 'If it was brought up, you could tell, you know, it made him angry,' she told OregonLive.
Neighbors had also raised alarms, with a group of residents at one point writing to Whitman's family urging them to intervene and get him mental health treatment. Lenzer said her son had been diagnosed earlier this year with bipolar disorder and schizophrenia following a mental health crisis that led to a stay at a Portland behavioral health facility after a suicide attempt. Court records show Whitman was subject to two separate 'red flag' orders—in 2022 and again this year—requiring him to surrender firearms due to concerns about potential violence. Two days after his most recent crisis, he gave up two guns.
'He showed signs of just being a perfectly normal person,' Lenzer said of his condition after being released from treatment. Yet she struggled to reconcile that image with the calculated nature of the attack. 'To think that hard about renting a car and the propane tanks and all the things,' she said. 'How do you figure that out and do that? Where did that come from?'
Earlier Stunt
Years before the deadly rampage, Whitman had made headlines for a far more unusual stunt—dyeing chickens pink using food coloring and beet juice and releasing them along Portland's waterfront in what he said was an attempt to 'make people smile.' The prank, while strange, ended without harm. But authorities now say the trajectory of his behavior took a far darker turn in the years that followed. His half-brother, Cody Erickson, said the two had maintained a relationship and described Whitman as adventurous and outdoorsy. 'He was a good guy, I thought,' Erickson said. 'I don't know. People change, I guess.'
Club Response
The Multnomah Athletic Club is one of the largest private athletic and social clubs in the United States with more than 21,000 members and has been closed indefinitely following what it called a 'significant incident.' General manager Charles Leverton acknowledged the shock spreading through the community after footage of the crash began circulating. 'While much remains unknown and the investigation is ongoing, it is clear that this is a difficult moment for our entire community,' Leverton said in a message to members. 'MAC has always been more than a building. It is a place where relationships are formed and people come together in good times and in challenging ones.'
