BUFFALO, N.Y. (WKBW) — There are major questions about transparency inside the Erie County Sheriff's Office. This comes almost a year after Chief of Narcotics and Intelligence Dan "DJ" Granville is accused of hitting seven parked cars while he was driving a county-owned truck on Buffalo's west side.

Granville's sister-in-law, a Buffalo police lieutenant, signed off on the police reports from the crashes. There is no indication drug or alcohol testing was done at the scene. Now, a Buffalo police internal investigation is underway.
But as allegations of a cover-up loom large, Erie County Sheriff John Garcia says these are just allegations and this was just a car accident.

As a candidate for sheriff, Garcia told 7 News I-Team Investigator Ed Drantch that he would be tough on transparency.
Drantch: How do you increase transparency and how do you increase that public accountability?
Garcia: Transparency is so important. As a resident of Erie County and as a voter, I want to know what's going on with my elected officials. It's very important to have transparency, that public trust and we will have that from day one. The way we will have it is always be in front of the issues. If something does go wrong, you get in front of it.
Despite being tough on transparency then, the sheriff didn't say anything about this crash for a year.

Now, Buffalo and Erie County lawmakers are demanding answers about the alleged cover-up involving Granville.
County lawmakers have set a date for when they are launching their own investigation. Erie County Legislature Chairman Tim Meyers said the Legislature plans to hold a meeting next month to get to the bottom of what happened.
"This whole thing is about getting the truth," Meyers said. "I want the truth. Everybody wants the truth. So that's what we're going to try to get, and we're going to try to do it in the most efficient way that we can."
He added that lawmakers are waiting for key details before moving forward.
Buffalo's Police Oversight Committee meeting is set for April 17. The Legislature’s meeting is set for April 24.
Meyers confirmed he is requesting that the sheriff, county attorney and Granville attend to answer questions.
