Police notified the family of a 17-year-old missing from St. Paul that they found video showing him jumping from a bridge, the police department said Tuesday.

Chuejee Thao, a Highland Park Senior High School student, was last seen on the Robert Street Bridge in downtown St. Paul on April 15, according to his family.

Police and his family previously asked for the public’s help in looking for him.

Police are now working with the Ramsey County sheriff’s office to search for Thao in the Mississippi River, but it has been difficult due to flooding, according to a police spokesman.

Thao’s family is grieving and trying to get closure, his sister, Pa Kou Thao, wrote on a fundraising website, gofundme.com/chuejeethao, on Tuesday.

The donation site was originally established because Thao’s family members were taking time away from their jobs to search for him non-stop. Now, the fund will be used for burial and funeral expenses, Pa Kou Thao wrote.

“For those of you who are still searching for my brother, we cannot thank you enough,” Chuejee Thao’s sister wrote. “… Wherever you can walk or bike along the river, please keep your eyes peeled. If you have access to a boat and are out on the river, please be on the search for my brother.”
