Callaghan said he plans to sue Moore and Glanden individually, as well as their respective agencies.
Thornsbury was indicted Aug. 15. Callaghan said he sent out the notices the following day.
"Basically, I knew my clients had been, for lack of a better term, done wrong, and their constitutional rights were violated," Callaghan said.
A spokeswoman for the Supreme Court acknowledged receiving Callaghan's letter. An employee of the Mingo County Commission, who declined to provide her name, said she was told to say, "I cannot confirm or deny anything at this point."
A State Police spokesman didn't return a phone message, and attempts to contact the city of Gilbert were unsuccessful.
It's difficult to guess how much money the Woodruffs could receive if their civil lawsuits are successful, Callaghan said. In cases that involve money, there's a base point from where a jury could start. An attorney can ask for damages on top of that amount.
"It's hard to put a dollar amount on the deprivation of someone's constitutional rights," Callaghan said.
"When you look at what my clients went through . . . I don't know how you put a dollar figure on that."
Of those Callaghan plans to sue, Thornsbury is the only one facing criminal charges in connection with Robert and Kim Woodruff. That means some of the civil lawsuits could be resolved before the judge's criminal case is completed, Callaghan said.
The state Supreme Court has suspended Thornsbury and appointed several judges to serve in the interim.
Thornsbury pleaded "absolutely not guilty" in a recent federal court appearance. A hearing for pretrial motions is scheduled for Sept. 26, with a jury trial slated for October.
