Haven't been able to find out much about Mary Ann Kricko, other than she practices general law. She doesn't seem to be very well known in the industry.
The only court case I could find (so far) is one where she and her partner (Gilberto Garcia) represented a number of illegal immigrants in a case filed against Walmart (Walmart had hired them, and then the undocumented aliens had been arrested in a raid that the U.S. govt conducted nationwide, so now they were suing Walmart for illegal trafficking and exploitation of undocumented aliens).

An interesting case, but can't help but wonder if she has any experience in capital murder cases?
