Suspecting trouble at Karen Mitchell's house, Hooker, Romano, Corrigan and Stacy race to the scene. They arrive as her killer is making his escape. Corrigan, who had been working undercover surveillance, is clearly seen wearing blue jeans and a brown leather jacket.
The suspect is chased through some hedges to his car. He attempts to run down the officers and throws Hooker off his car while making his getaway. During this sequence, Corrigan is somehow now in his full police uniform with jacket.
After checking to see if Hooker is alright, they return through the hedges to the house. At this point, Corrigan magically reappears in his undercover civilian jeans and brown jacket.
