It was the last day of his term that Sunday, Oct. 17, 1920, and a seemingly relaxed Percival had decided not to run again after his one-term stint.
That morning, he strolled across the relatively new Interstate 5 Bridge, then called the Interstate Bridge, which opened on Feb. 14, 1917. Prior to becoming mayor in 1918, he supported the bridge project as a city councilor, something that caused the same controversies back then as the modern CRC project has caused over the past decade.
Later on the cold, rainy morning, Percival was seen wandering back over the bridge to Vancouver, then over to Seventh Street at around 11 a.m.
He wasn’t seen again until 3 p.m., when he briefly appeared on 26th Street, still ambling along at a leisurely pace.
After that, nobody saw him at all.
Not the next day, when a victorious John P. Kiggins celebrated the start of his second of four non-consecutive terms as mayor. Not a week later. Not even a month later.
“That was the great mystery of the day,” said Pat Jollota, a Vancouver author, history buff and former city council member. “He was seen downtown tipping his hat, and then he just disappeared.”
On Monday, Oct. 18, all the downtown stores closed at 1 p.m. A group of 285 Vancouver businessmen, divided into 18 search parties, hit the streets searching for the missing mayor.
They searched the district between 26th Street and Vancouver Lake. They searched Felida. And they searched the Columbia River for a body.
They found nothing but a handful of false leads.
“It would be just like we finished building the CRC and then the mayor disappeared,” Jollota said.
A dark discovery
It wasn’t until Nov. 22, long after the trail had gone cold, that Portlander O.F. Williams decided to take a shortcut through the wilderness on his way home from the Kenton neighborhood. There, “in a clump of trees about 100 yards from the Oregon approach to the Northbank railroad bridge,” Williams found Percival’s body hanging from a tree, said a report in The Evening Columbian.
“According to those who saw the body, there is every reason to believe that Mr. Percival took his own life. His personal papers and some jewelry and some money were still on his body,” the story said.
But that conclusion has never sat quite right with Jollota, she said.
“What if he didn’t kill himself,” she said. “I’ve wondered for some time if he was, indeed, murdered.”
The night before he vanished, Percival attended a port commission meeting “and seemed somewhat nervous,” an Oct. 17 story in The Evening Columbian said.
But his finances were in order, he wasn’t depressed about the election because he wasn’t a candidate, and he seemed to be looking forward to returning to his successful insurance business, Jollota said.
“He was seen in a good mood on the day he vanished,” Jollota said.
Still, after the grisly discovery, “no inquest was held over the body as it was obvious that Mr. Percival had taken his own life,” a Nov. 23 story in The Evening Columbian said.
