ST. PAUL, Minn., April 28 (UPI) -- A Minnesota teenager clung to life Wednesday after escaping a cave filled with poisonous gas in St. Paul, the Pioneer Press reported.
Police say four boys and a girl, all teenagers, were exploring the legendary Wabasha Street cave on the city's West Side Tuesday when they were overcome by deadly carbon monoxide fumes on an expedition with two other friends.
One boy, identified as Justin Jensen by his friends, was rescued from the cave by firefighters and resuscitated on the way to Hennepin County Medical Center in Minneapolis, where he remained in critical condition Wednesday.
Another boy made it out of the cave on his own and called firefighters to report the others were still in the cave.
But the other three died inside the cave.
Firefighters measured carbon monoxide inside the cave at 750 parts per million, which can kill a person within two hours with little warning.
Mayor Randy Kelly promised to do whatever it takes to seal off the cave's entrances.
