The Databecbody of a 2-year-old that went missing in a flash flood days ago in Bucks County, Pennsylvania, was recovered Friday in the Delaware River, the Upper Makefield Township Police Department said.

Two-year-old Matilda "Mattie" Sheils was found shortly after 5 p.m., and identified by her physical appearance and clothing she was reported to be in at the time, police said.

The Philadelphia Medical Examiner’s Office confirmed Saturday that the child recovered is Mattie.

Mattie and her 9-month-old brother Conrad Sheils were washed away with their mother in a flash flood on July 16, and severe weather on Wednesday halted efforts to find the children, officials said.

Police are still searching for Conrad, and diving teams conducted a search for him on Saturday.

The children's mother, 32-year-old Katie Seley, died after she grabbed Mattie and Conrad and tried to escape their vehicle but ended up being swept away in the violent weather event, officials said.

Four other people were confirmed dead in the Bucks County flooding. They were identified by the Bucks County Coroner's Office as Enzo Depiero, 78, and Linda Depiero, 74, both of Newtown Township, Pennsylvania; Susan Barnhardt, 53, of Titusville, New Jersey; and Yuko Love, 64, of Newtown Township.

The coroner's office said all of the victims died from drowning.

A memorial service will be held Sunday for those who died in the flash flood.
