UPDATE (9:38 a.m. Thursday): Uber lawsuit purportedly filed by accused mass shooter is bogus

DETROIT, MI - Kalamazoo mass shooting suspect Jason Brian Dalton is suing Uber and claims the ride-sharing service "treats their drivers like crap" and is to blame for him being held in the Kalamazoo County Jail on murder charges.

Dalton's two-page, hand-written complaint was mailed March 11 and filed Tuesday in U.S. District Court for the Eastern District of Michigan in Detroit. He seeks $10 million in punitive damages from Uber Technologies Inc.

He says the company caused him emotional distress and he has "psychological damage because of Uber."

"I worked years as a Uber contractor and they ripped me off, never paid me back wages or overtime," Dalton said in the complaint. "I busted my butt for them. They gave me no Christmas bonus, I wasn't invited to any corporate parties, they made me work when I was sick and didn't let me spend time with my 2 children."

Police and prosecutors have said Dalton, 45, of Cooper Township, was working as an Uber driver on Feb. 20 when he is accused of going on a shooting rampage in and near Kalamazoo that left six people dead and two others seriously injured.

In police reports obtained by the Kalamazoo Gazette and MLive earlier this week, Dalton told detectives he was possessed by the Uber app on his iPhone during the mass shooting and remembered little about what happened. Dalton told detectives the Uber app turned him into a "puppet" and led to the carnage.

Dalton has been charged with six counts of murder, two counts of assault with intent to commit murder and eight counts of felony firearm use in connection with the mass shooting. A judge has ordered Dalton to undergo an evaluation to see if he is mentally competent to stand trial.

Uber officials have said previously that Dalton was cleared to become a driver for the company Jan. 25 after passing a criminal background check. The company has acknowledged it received complaints that Dalton was driving erratically Feb. 20 but has declined to say how it responded to those complaints.

In his lawsuit, Dalton called Uber a "hostile workplace environment" and complained the company treated him like "a "2nd class citizen" and "discriminates against my mental health."

"Uber treats their drivers like crap," Dalton said in the lawsuit. "I had to pay my own gas and I hit lots of potholes and Uber would not fix my Chevy Equinox and Uber would call my phone late at night and make me work or say I was fired. ... I am currently in prison because of Uber.

"Uber doesn't care about its driver. We are peasants and pawn pieces to Ubers bottom line. Defendants manipulate all Uber drivers. My life is ruined because of Uber. My wife is divorcing me because of Uber."

Dalton seeks a jury trial. The case has been assigned to U.S. District Judge John Corbett O'Meara.
