Dozens of friends and relatives of Joey Kaiser spent Memorial Day retracing their steps to see if they overlooked clues as to what happened to the St. Paul teenager missing since last Tuesday.
"Anywhere we can think of that Joey might have gone, that's where we're going," Jennifer Kaiser, his 19-year-old sister, said Monday afternoon.
Authorities focused their search on the Mississippi River after Friday night, when a passerby found what could be the 17-year-old's bike in bushes on a river bank at Mississippi River Boulevard and St. Clair Avenue. Officers spent Saturday combing the river and the bushes, but found no trace of the teen.
Police won't let the family see the bicycle until today because they wanted to conduct DNA tests on the bike.
Jennifer Kaiser said her father saw the bike on TV and believes it is his son's.
"We're about 95 percent positive it's his," she said. "The bike that Joey has is extremely distinct. ... There's only one of them out there."
Family members could not see whether the bike on TV had a missing pedal like Joey's bike, she said.
Dogs searched the riverbank Saturday but didn't find a scent trail, she said.
On Sunday, more than 200 volunteers scoured the Twin Cities, suburbs and the riverbank. Among the places searched were storm drains feeding into the river because Joey Kaiser liked to explore them, his sister said Monday.
She said searchers also checked in downtown St. Paul to see whether her brother might have gotten on a bus.
"The search is still going on; [police] can't do anything else until they have another lead," she said Monday. "It's been a hard weekend for us."
