A Lawrence man accused of making bomb threat calls last week in Douglas County made a brief court appearance Tuesday morning. Judge Stephen Six set Michael E. Parker’s next court date for a week later.

Defense attorney J.C. Gilroy stood in for Parker’s appointed attorney, Jim George. Six scheduled the appearance for next Tuesday so George could attend.

Police arrested Parker, 46, on Thursday, after emergency dispatchers received threatening calls that mentioned schools and a city hall. The calls forced administrators at schools and city halls in Douglas County to be on alert, and thousands of students went home early.

Lawrence city leaders have said the city denied an insurance claim recently that Parker had made alleging that he tripped on a loose brick downtown and injured his shoulder.

Prosecutors charged Parker with three counts of making an aggravated criminal threat after three school buildings in the county were evacuated. Parker remains in the Douglas County Jail on $30,000 bond. He faces a maximum of 46 months in prison on each count, if convicted.
