Magdalena Jablonska of Des Plaines was a U.S. Marine veteran. Her fiancé, Alan Telmini, survived the boat collision and is still recovering.
Telmini said she didn't have to die that day. He said Magdalena Jablonska, or Maggie as she went by, was happy out on the water.
They had taken a swim earlier and even brought their dog on the boat with them.
Their dog, Sasha, was actually sitting on Jablonska's lap when the crash happened.
According to the wrongful death lawsuit filed Wednesday, on July 25, Jablonska was sitting next to her fiancé on their boat when a speeding boat flew over them, decapitating her and seriously injuring her fiancé.
Richard Stevenson was charged with reckless homicide and aggravated driving under the influence causing death in the crash and is accused of having a blood alcohol level more than twice the legal limit.

The lawsuit alleges he was driving 80 miles-per-hour as he approached a no-wake zone on the Fox River.
Security footage from a nearby home allegedly shows the 30-foot pontoon Stevenson was driving.
Jablonska fiancé fought back tears Thursday morning as he described the horrific collision.
"I heard loud engines, and I looked to the left. And Maggie, she was gone," he said. "I relive that moment every day, a few times. We want to make sure justice is served and other people out there don't get treated like that, as well."
"We're talking about a very wealthy family that has an incredibly successful wealthy corporation that enables their spoiled son to go out and buy a half million-dollar boat for cash, live on his boat, party on his boat, be a menace to the community, driving his boat 70, 80 miles-an-hour around, scaring the heck out of people, taking people's lives. And he is a vice president of a company that his mom owns," said Louis Cairo, the victim's attorney.
Jablonska's sister, Michelle Macias, said she's being remembered as a kind person, who enjoyed serving people in need.
"This didn't have to happen," Macias said. "She was a really good person, always taking care of other people for the longest time ever. I remember I used to tell her all the time, can you do something for yourself?"
Macias said her sister played a major role in her life.
"I wish I could hug her one more time or hold her hand one more time," Macias said.
The family's attorney said this is about getting a dangerous boater off the water.
By filing this lawsuit, they can obtain every piece of evidence, including what kinds of alcohol may have been purchased and video evidence to paint a picture of the driver's condition that day.
"Anyone with information, whether it's a Ring camera, it's a cell phone, it's a video, it's names of witnesses that know anything about this person's conduct, his consumption of alcohol, how he was acting, things of that nature, how he was operating the boat, um, we need that. The criminal justice system needs that," Cairo said.
Family members also shared a video Jablonska recorded with her dog about 30 minutes before she was killed.
Jablonska's birthday is Aug. 27, and her family plans to hold a memorial on the Fox River that day.
"It will be very difficult to go because there were a lot of places we had been, a lot of memories," Telmini said.
Macias said she continues to think about how her sister would handle the situation.
"I just all the time try and remind my self what she would be doing for me if things were different because she was a lot stronger," Macias said.
Stevenson remains in custody and is scheduled to return to court Aug. 21. Jablonska's wake is planned for Sunday.
