"He's been wrongly taken from us," O'Gara's ex-wife Leanna O'Gara said.

"He's been through everything in his life, but he always took care of his family, no matter what," she added through tears. "He loved everybody. He loved all of us. He was part of the glue of this family, and now he's gone."

Leanna said O'Gara described the pride he had for his children the day before he died.

"He'd just told them, 'I'm so proud of you guys,'" she said. "And they are, I don't know, I don't know what to do. I don't know what to tell them. It's not fair. It's not right."

She said O'Gara's 11 children and six grandchildren often called him "Papa Mark."

"He's hard working," his 11-year-old daughter Katie O'Gara said. "He's brave."

Leanna said Mike followed his dream about a year ago and opened up his own business as a tile setter.

"His voice, his caring and his love," his nine-year-old granddaughter Aubree Johnson said when asked what she'd miss most about her grandpa.

Authorities say 19-year-old Jose Vasquez Guillen was driving a vehicle in St. Paul, heading southeast on Concord Street, when he struck O'Gara's vehicle as O'Gara was pulling out of a driveway near Page Street.

Alcohol is suspected as a factor.

Authorities said Guillen has been arrested, but has not yet been charged. St. Paul police say the investigation is ongoing.

Meanwhile, Leanna said one of O'Gara's previous employers has offered to help with funeral expenses.

A viewing is scheduled from 9:30 to 11:30 a.m. Monday at the Salem Lutheran Church at 11 Bernard Street in West St. Paul. A service will follow from 11:30 a.m. to 12:30 p.m.

The family has set up a Go Fund Me.

"Nothing is worth this," she said. "There's no reason for any of this. There's not. And I feel bad that this young (man), whatever situation that caused him to be drinking and driving. Obviously something happened in his life."
