Declan Berry has been missing since the blue VW Polo he was driving plunged into the River Nene at North Brink in Wisbech on March 17.

There were five people in the car. Three of the passengers, two girls aged 16 and a man aged 18, managed to escape the vehicle.

However, 16-year-old Eden Bunn, from Sutton Bridge, died in the crash, with her body being recovered by emergency services from the river.

Sadly, Declan's body has yet to be found despite extensive searches by specialist teams, police, and a police helicopter.

In a post to Facebook on Monday morning, Declan's parents posted a message thanking the emergency services for their work so far in trying to recover their son's body.

Now the family, who have continued to search for Declan every day, have asked for help in clearing the debris from around the pontoons at the harbour off Nene Parade in Wisbech.

"We are still looking for Declan, my son, who was in a tragic accident, and his car went into the river," Alan, Declan's father, said.

"The family has been searching every day and I saw the fire service driving up North Brink.

"We would like to say thank you to everyone who has helped us look and those who are still helping.

"I need some help about how to get the pontoons cleared of all the debris around them in case Declan is trapped among the debris.

"We would appreciate any help to find Declan and lay him to rest."

A GoFundMe appeal has been launched to help Declan's family at this heartbreaking time.

It has been set up by a family friend, Donny West, who described Declan as a hardworking, determined and dedicated young man with his whole future ahead of him.

"After much thought and consideration, and with the full support and consent of the Berry family, we have set up this GoFundMe to help ease any pressures and stress they may be facing," he said.

"Our aim is to allow them the time and space they need to grieve and to focus on one another, as well as to support them in giving Declan the dignified and meaningful send-off he truly deserves, when the time comes."

A GoFundMe has also been set up in memory of Eden, to help her family, parents Lisa and Dean, sister Shelby, and brother Jay, to give her the best send-off possible.

Jasmin Rauch, who launched the page, described Eden as a "much-loved daughter, sibling, granddaughter, niece, and auntie - to Axl".

"Eden was not only a much-loved young lady to her family but also to her friends," she added. "A truly remarkable, kind, thoughtful and caring young soul who has been taken far too soon."
