CHICAGO: An Uber driver who may have picked up fares during a weekend killing spree was headed to court Monday to face charges of murdering six people in the northern state of Michigan.

Kalamazoo County Prosecutor Jeff Getting said local law enforcement agencies were still assessing all the crimes 45-year-old Jason Brian Dalton will be charged with at an arraignment later in the day.

“I anticipate out of that review will come six counts of murder, two counts of assault with intent to commit murder, and eight charges of what we call felony firearm, using a firearm during the commission of a felony,” Getting told CNN on Monday.

“Murder charges carry life in prison without the possibility of parole. The others, life sentence with parole.”

Uber confirmed that Dalton was a driver for the ride-sharing company, adding he had passed a background check and had no criminal record.

“We have reached out to the police to help with their investigation in any way that we can,” Uber’s chief security officer, Joe Sullivan, said Sunday in a statement.

Uber’s tracking system would show the location of Dalton’s vehicle during the chain of shootings Saturday night that left six people dead and two seriously wounded at three different locations, officials said.

A woman was seriously wounded outside an apartment complex, two people were killed at a car dealership, and four more were shot dead at a restaurant, where a 14-year-old girl was also seriously wounded.

Kalamazoo’s public security chief, Jeffrey Hadley, said police were looking into reports Dalton picked up fares between shootings.

“I think as soon as we are able to latch on to the information in terms of his whereabouts in between the first and second shooting and second shooting and third shooting we will certainly understand where he traveled to and maybe lead us to other sources of information,” Hadley said in a CNN interview.
