Tammy Anquinette Thomas has been a model inmate at Anoka County jail the last four months.
When she becomes Jane Doe at her court proceedings, it's another story.
The 37-year-old nurse, who last lived in a small town in Illinois, refused to let police take fingerprints or her mug shot after she was arrested and charged with burglary in July. Deputies eventually lifted her prints off a drinking glass.
She's had no visitors, made no telephone calls and written no letters.
She won't respond in court unless addressed as Jane Doe, and refuses to cooperate when county experts try to determine whether she is mentally fit to stand trial. In a nearly unprecedented order last week, a judge sent her to the state hospital in St. Peter to give doctors another chance to measure her competency.
Only Thomas knows why she is being so secretive, but authorities said she probably would be out of jail by now had she abandoned the silent treatment.
"She is perfectly content remaining in jail and maintaining she is Jane Doe," said Cmdr. Paul Sommer of the Anoka County Sheriff's Office. "Most people do whatever they can to make bail and stay out of jail."
Name is known, but little else
