RTV6 reporter Julie Pursley said 125 prospective jurors filled out special questionnaires last week with questions about whether or not they'd seen media coverage of the case, if they thought they could be fair and impartial, and other such questions.
Based on the answers given, the prosecution and defense agreed that 17 of the respondents should not serve on the jury.
In court Monday, lawyers and Judge Carlisle were going through each remaining questionnaire one by one to determine, based on the answers, which potential jurors could and could not qualify to be on the jury.
After considering each questionnaire, Judge Carlisle could determine whether or not a change of venue is necessary.
Leonard, his former girlfriend Monserrate Shirley and his brother Bob Leonard face charges of murder, arson and conspiracy to commit arson in the November 2012 blast that killed two of Shirley's neighbors and wrecked dozens of houses in the Richmond Hill subdivision on the city's far south side.
Prosecutors allege the three set the blast in Shirley's home as part of a scheme to collect insurance money.
Mark Leonard, Bob Leonard and Shirley are being tried in three separate trials.
