Columbo Isn't On The Case

I committed murder and I have bad news.
Columbo is on the case and that means I'll lose.
Columbo always catches people when murder is the crime.
He always uses his skill as a detective but not this time.
I just went inside the Police Station and confessed that I'm guilty.
Columbo is hopping mad because he won't be able to catch me.
The cigar smoking cop is so mad that he's starting to shout.
A murder was committed and he didn't get to figure it out.
