WATCH New Details About Uber Driver Accused in Kalamazoo Shooting

The family of an Uber driver accused of going on a deadly shooting spree in Kalamazoo, Michigan, last weekend has expressed their sympathy to the victims, according to the family's attorney.

Jason Dalton, 45, was arrested early Sunday morning after three separate shootings that killed six and injured two, including a 14-year-old girl who was critically wounded.

Attorney Paul Vlachos told ABC News that what's important to the family is "remembering the people who were hurt."

Vlachos also revealed new details about Dalton's behavior in the days leading up to the shooting rampage, saying he was told by Dalton's wife, Carol, "he's been acting differently in the last couple of days and his wife asked him and he said he was tired." When asked by ABC News' Alex Perez about what made Dalton's wife think he was acting differently, Vlachos said, "just his demeanor, that he seemed to be depressed and down, which was not his normal character."

Vlachos said that ahead of the shootings on Saturday, Carol was out running errands with the couple's children, a 10-year-old daughter and 15-year-old son. Dalton spent the day with a friend, visiting a gun store before picking up Uber passengers.

At some point after the shootings began, Vlachos said Dalton called Carol and asked her and the kids to meet him at his parent's home. When they got there, he told them that the Chevy Equinox that he was driving for Uber had been side-swiped by another vehicle and took his parent's Chevy HHR to continue picking up passengers.

Before Dalton left, he told his family to stay put at his parent's house, according to Vlachos. Later, once authorities had arrested him, they came to Jason's parent's house, having found their address on their car's vehicle registration.

According to Vlachos, Jason had started driving for Uber within the last two weeks, often spending many of his evenings picking up fares. He was also employed as an insurance adjuster.

"Jason by all accounts was a fairly gregarious character. A good father. Well-known in the community. Well-liked. There was nothing to indicate that something like this would occur," Vlachos said.

He denied reports that the family was experiencing financial troubles and said that the couple was not estranged at the time of Dalton's arrest, as other outlets have stated.

Dalton is charged with six counts of murder, two counts of assault with intent to commit murder and eight counts of using a firearm during the commission of a felony, according to Kalamazoo County prosecuting attorney Jeff Getting. He has not yet entered a plea.

Attorney Eusebio Solis has been appointed to represent Dalton, according to the Associated Press. Solis has not responded to ABC News' request for comment.

Ed Davis of the Uber Safety Advisory Board told "Good Morning America" Monday that there was "no background check that would have identified this man as a problem."
