COLLIER COUNTY, Fla.- Investigators tell WINK News they plan to be back out at the site of Monday morning's accident on Alligator Alley. A mother and her two young daughters died after the car they were in hit a box truck then plunged into a canal.

A family friend, who's known the Douglas family for a decade and was even a part of their wedding, told us he'll be at the funeral for Cecilia, Madison and Rylee on Saturday.

"They're still struggling of course trying to make all the funeral arrangements," said Eagle.

The accident scene has been cleaned up. There were just some tree branches around, but the fence and pole are back up and standing. Florida Highway Patrol and the Department of Transportation both say they need more information about this tragedy.

Family friend Don Eagle says Nathan, the man who lost his wife and two daughters, is constantly surrounded by friends and family, though Eagle hasn't spoken to Nathan about the accident.

"It's mentally and emotionally a trying and draining thing and of course i'm not sure they're completely with their feet back on the ground yet because of it," he said.

The Douglas family is relatively new to Collier County, but Eagle says Nathan is very aware and very grateful for the outpouring of support he's been receving from people in this county.

"It is with their heartfelt thanks that they wanted me to say to each of those people, thank you and they wish they could you know personally address each and everyone of them, but at this point, you know they're just so overwhelmed," said Eagle.

The funeral and burial service for all three will take place Saturday at their church in North Florida.
