Three more victims of last week’s deadly bus crash have been laid to rest Thursday, as family members spoke of coming to grips with the fact they'll never see their loved ones again.

Kyle Nash, a 21-year-old Carleton University student with dreams of being a game developer, was remembered by a crowd of around 350 people at a morning service in Barrhaven’s Cedarview Alliance Church.

Nash's father Richard said his family has had a part of them cut out and they just want him back.

"It's been a hell of a week,” said Richard Nash.

“We have gotten over the initial shock and disbelief of that awful day. Now it's replaced with certainty and assurance that after the craziness of this week, we will live our lives with an incredible void."

Friends said Nash was likely sitting beside his friend and fellow Carleton student Connor Boyd when the OC Transpo bus they were riding crashed into a VIA Rail train at Fallowfield Station, killing those two and four others, while injuring over 30 people.

"This is a horrible shock..." said Ernie Domitrovits, a friend of the Nash family.

"It's just an unimaginable tragedy."

Nash’s funeral was held the same location as the service for Boyd on Monday.

A service for Michael Bleakney, an engineer and Atlantic Voices choir member, was on Wednesday.

Karen Krzyzewski 'a loving person'

Shortly after Nash's service ended, hundreds more people gathered at Woodvale Church in west Ottawa to honour the life of Karen Krzyzewski, a 53-year-old mother of two who worked at Library and Archives Canada for 28 years.

A statement from her family said Krzyzewski was passionate about the role of libraries in Canadian society, while a statement from her employer described her as a talented knitter.

"She was a loving person," said colleague Jon Fotheringham. "She gave herself... to an incredible degree." 

Friends and family spoke after her casket was carried out by her immediate family and said the service was "beautiful."

"It really hit home how much something like this affects people, especially when they're so close to you," said Fotheringham.

'It leaves a huge hole in our heart'

Rob More’s funeral began at 1 p.m. at the Capital Memorial Chapel in south Ottawa, ending with his family carrying an urn filled with the 35-year-old's ashes as the former Hockey Night in Canada song played.

More lived with cerebral palsy and loved sitting at the front of double-decker buses’ top level, according to his father, who said he now has a front seat to every sports game with his grandfather.

"He was a very witty person, he loved sports," said his friend Shamil Jessa. "He was just a really sweet, gentle guy."

"It's a tragedy. It will take a while for everyone to get over it," said friend Melanie Fournier.

"It leaves a huge hole in our heart."

Amateur crash video turned over to police

Ottawa police said Thursday they had possible new information about the Sept. 18 crash.

They said a man has passed along amateur video of the crash, which will be added to evidence being gathered.

The Transportation Safety Board of Canada is continuing its investigation to determine the cause of the crash.

The memorial service for driver Dave Woodard is being held Wednesday, Oct. 2.
