As dispatchers listened for almost 20 horrifying minutes, four teenagers trapped in a Hudson home were shot at repeatedly by a man who was later critically wounded by deputies early Sunday morning.
St. Croix County authorities said that among the targets of Daniel Christenson, 43, was his 19-year-old son Zach, who not only managed to escape getting shot by his father but also was able to call 911 shortly before 6 p.m. Saturday.
Investigators also credited the younger Christenson with saving the lives of his three friends by leading his father away from them during the shooting spree and then breaking a bedroom window in the basement so all four of them could escape unharmed.
Nearly seven hours later -- shortly before 1 a.m. Sunday -- authorities ended a standoff that involved nearly 50 officers by lobbing chemical projectiles into Christenson's Wisconsin home. Police said Christenson was wounded when he came out of the house and shot at a deputy, who returned fire. No officers were injured in the exchange.
Christenson was listed in critical condition at Regions Hospital in St. Paul on Sunday with wounds to his stomach and chest.
The deputies who shot at Christenson were placed on paid leave pending an internal investigation, which is standard, said John Shilts, the chief deputy at the St. Croix County Sheriff's Office.
Investigators estimate Christenson fired dozens of shots inside and outside the home, shooting up areas of his bedrooms, hallways and basement.
"There were numerous bullet holes everywhere," said Lt. Paul Larson of the Hudson Police Department.
