Grubbs wants to know if the Shelbyville park is operating ethically, legally and in line with state guidelines for Certified Technology Parks, according to The Shelbyville News.
Intelliplex as well as parks at Purdue University and elsewhere in the state are up for recertification this year.
Grubbs' letter questioned whether land was sold to private-sector buyers at too low of a price. She also asked about an "immediate appearance of conflict of interest" between Shelbyville Mayor Scott Ferguson and Ferguson's father-in-law, Lee McNeely. McNeely's law firm built offices and a public and private conference center at Intelliplex.
In early April, Major Hospital, the Shelbyville hospital that played a pivotal role in starting the park in 2003, posted on its Web site answers to 180 questions fielded from the community.
The following month, about 100 people showed up at a session where they could question officials about the park.
In the meeting, hospital President Tony Lennen told the crowd that Indianapolis real estate brokers say more tenants would move into the park if it were not for "an attitude of negativity and distrust in the community."
