KALAMAZOO, Mich. – The Kalamazoo County Sheriff’s Office says that a report about Jason Dalton filing a lawsuit against Uber after being accused in a shooting spree that killed six people is a hoax.

Undersheriff Paul Matyas tells FOX 17 that the lawsuit that was picked up by major media, including the Associated Press, was not filed by Dalton nor on his behalf.

Matyas says he was suspicious when he saw that the envelope containing the lawsuit was postmarked from Philadelphia.

Matyas says that Dalton did not send it, did not authorize anyone to send it and does not know who sent it.

The lawsuit was listed in federal electronic records as being filed by Dalton in U.S. District Court in Detroit and was given a case number.

Dalton is charged with killing six people and wounding two others in a shooting spree in Kalamazoo on February 20. He was driving for Uber, the ride share company. He has told police that he felt that he was being controlled by Uber.
