"We're messing around (with) people's lives and their children," Adams told the news site. "It just seems beyond irresponsible to the point of being callous about the consequences."

Two women who say they lost custody of their children due to Murrah’s alleged actions filed a lawsuit Tuesday against her. Adam Jones, who represents Amy Farver and Tiffany Long, is seeking class action status for the complaint.

"This is maybe the most troubling case I've ever had," Jones told WTVY in Dothan.

Jones told the news station that tests done by Murrah’s lab indicated both of his clients had methamphetamine in their systems, causing the Alabama Department of Human Resources to remove their children from their homes.

"Both of these ladies went to independent drug testing facilities and medical clinics and got more drug testing done, and all of it was negative," Jones said.

The women have not regained custody of their children, the attorney said.

If the lawsuit obtains class action status, it would represent “all persons who have submitted urine, blood, hair or other biological specimens to the defendants for testing, with said testing being performed incorrectly, reported incorrectly or not performed or reported at all.”

Adams told AL.com he expected more criminal charges to be forthcoming against Murrah, possibly to include additional forgery charges, as well as theft and perjury charges. Theft charges would stem from tests Murrah was paid to perform but didn't, and perjury charges would evolve from any cases in which she testified under oath about falsified results.

Murrah was not involved in any criminal cases, AL.com reported. There have been no indications she was paid to change the outcome of any cases.

The district attorney said it was not yet clear how many custody cases were affected by Murrah’s alleged crimes.

"We have no idea at this time how many people did not get their children back because of Ms. Murrah's alleged fraudulent reports," Adams told the Eagle. "I am furious and offended by these alleged crimes. I don't understand how someone could be so callous and evil, to have no regard for the consequences of their actions. In my opinion, all cases affected by Murrah's alleged actions must be redone in order to be fair.

Murrah's attorney, David Harrison, told the newspaper his client is innocent until proven guilty.

"We are looking forward to going to court, and I believe a lot of information will come out during court," Harrison said.

The forgery charges are not the first criminal charges filed against Murrah. Court records show she pleaded guilty in 2013 to five counts of fraudulent use of a credit or debit card, the Eagle reported.

She served three years’ probation in the Houston County case.
