DENVER -- When Katie Medley gave birth to a healthy baby boy at University of Colorado Hospital, her husband Caleb, wounded in the theater shooting, lay in a medically induced coma one floor below.

Hugo Jackson Medley was born at 7:11 a.m. local time yesterday, said hospital spokesman Dan Weaver. who added that mother and baby were doing great.

Caleb Medley, an aspiring comic, has undergone three surgeries since Friday's shooting during a showing of the new Batman movie at a multiplex in nearby Aurora that left 12 people dead and dozens injured. Katie was unhurt.

Caleb Medley is on a ventilator but starting to breathe on his own and can squeeze people's hands, family friend Michael West said. His heart rate shot up to 130 beats a minute whenever anyone talked about the coming baby, who was named before his birth, he said.

"He is showing signs of improvement," said West, who is leading an online effort to raise money for the family, which doesn't have health insurance.

West said Katie Medley had been scheduled to be induced and deliver her baby on Monday before the shooting but she changed hospitals in order to be close to her husband.

The couple went to the midnight showing of the "The Dark Knight Rises" as a last date before becoming parents.

Katie Medley's father, David Sanchez, spoke outside the court house where the shooting suspect made his first court appearance on Monday.

Since then, donations to the family have shot up to over $100,000.

Meanwhile, background checks for gun purchases spiked 43 percent in Colorado after the shootings, according to Bloomberg News.

Gun dealers submitted 2,887 requests for state background checks required to sell a firearm in the three days after Friday's shooting, said Susan Medina, a spokeswoman for the Colorado Bureau of Investigation. That's 43 percent more than the 2,012 requests during the same three days the prior week, and a 39 percent increase over the 2,078 check during the first Friday to Sunday in July.

Debate over gun laws after high-profile shootings often helps spark gun sales. Last year, one-day gun sales in Arizona jumped 60 percent after a gunman killed six people in a Tucson parking lot and wounded Rep. Gabrielle Giffords.
