BUFFALO, N.Y. (WKBW) — There are still many questions about what's happening in Buffalo schools after a Buffalo police detective came forward, claiming the district is covering up abuse.

One of those questions is if the Buffalo school system is cooperating with Buffalo police in turning over evidence, like surveillance video, once police ask for it to continue investigations.

Early last month, the 7 News I-Team requested all written communications, between Buffalo school security and Buffalo police, to see what the back-and-forth has been. This comes after SVU Detective Richard Hy said the district deleted surveillance video, from an attempted kidnapping, at the Buffalo Science Magnet school.
