A state investigation finds testing errors and shoddy record-keeping for the program that certifies colorado's paramedics and EMT's.
The investigation began when an employee of the Colorado Department of Public Health noticed a malfunction in the machine that grades medics' tests.
Since then, state health workers have been reviewing the certificates of more than 10 thousand emergency responders in Colorado.
What they found were at least 14 people were given passing scores when they actually failed and 5 failed when they actually passed.
State health workers also worry some people could have responded to emergencies without proper certification since last August.
