In Grand Junction. No details yet, but it sounds like he may have been injured somehow:

Authorities said Hsu was taken into custody at St. Mary’s Hospital in Grand Junction at 7 p.m. local time. He had been on the lam for almost two days after failing to appear in a Redwood City courtroom Wednesday to surrender his passport.

Stand by for updates.

Update: The feds are going to drop the interstate fugitive charge against him when they turn him over to California? Huh?

Update: Forty minutes later and the AP story is still the only game in town. While we wait for news, speculate away as to what he was doing in Colorado. A google search reveals no links there save for a donation Hsu made to Rep. Mark Udall’s senate campaign. Nothing unusual there; Hsu donated to Democrats all over the country. A commenter below says he’s surprised Hsu is still in the country but that’s really not surprising. He fled to Hong Kong after his first round of legal trouble in the early 90s. Airports would have been the first place the feds looked and Hsu surely would have expected it. Maybe he was driving cross country, back to familiar territory on the east coast, and got sidetracked somehow in Colorado?

Update: Plain ol’ rotten luck?

Hsu was traveling on an Amtrak train when he became ill. Grand Junction paramedics were summoned to the Amtrak station near downtown about 11 a.m. Thursday to treat a patient, Battalion Chief Robert Ferguson said.

The patient, whom Ferguson said he found out eight hours later was a fugitive, was not in great pain, Ferguson said.

“There was no extrication needed,” Ferguson said. “He walked out of the train on his own.”

He is currently in federal custody at St. Mary’s and is listed in fair condition, said St. Mary’s nursing supervisor Pete Smarr.

Update: The Chronicle says paramedics initially requested a backboard to move him. He boarded at Emeryville, California, says the Times, and was on his way to Denver.

Update: Interesting — he was hospitalized at noon but wasn’t arrested until 7 p.m.

Update: NBC’s Denver affiliate notes that ICE was involved in the arrest. Won’t that be a tasty angle if he’s here illegally.

Update: The detail about the backboard made me think he’d had some kind of acute spasm or something, but now the AP is saying he was “delirious” when he got to the hospital. Hmmmm.
