It's happened again. Another sign language interpreter

accused of signing total gibberish. This time

it was at the police news conference announcing

an arrest in the Tampa serial killings. We will

be charging four counts of first-degree murder.

Standing off to the side, apparently translating

every word, this woman. We received over 5,000

tips in this case. But it turns out, much of

what she was signing was nonsense. She waved

her arms around like she was singing Jingle

Bells, says one outraged sign language expert.

The woman, identified as Derlyn Roberts, has

a string of arrests for fraud. So how did she

come to be translating at last week's high-profile

police news conference?

I just didn't ask enough questions. Tampa Police

Public Information Officer Steve Hegarty told

me the woman simply showed up out of the blue

and offered her services. My immediate reaction

was, I didn't call for a sign language interpreter,

but that's great that we have one here. I let

her in. Did this woman appear to know what she

was doing?

To the untrained eye, and that would include

mine, um, I didn't see any problem.
