After plummeting 75 feet from a bridge into the chilly waters of the Willamette River, a 7-year-old is about to start life again; this time without her mother, who is charged with trying to kill her.

PORTLAND (AP) — A 7-year-old girl who survived a fall into the Willamette River that killed her 4-year-old brother is expected to be released from a hospital soon.

The girl's father, Jason F. Smith, 33, is grieving and still in shock but is trying to remain strong for his daughter and has been with her at the hospital, said his attorney, Laura Schantz.

"What I would say is she's keeping him going," Schantz said Wednesday. "He's absolutely devastated."

The girl's brother, Eldon Jay Rebhan Smith, died early Saturday morning after the children plunged about 75 feet into the chilly water from the Sellwood Bridge in Portland.

The children's mother, Amanda Stott-Smith, 31, is charged with aggravated murder and attempted aggravated murder.

Investigators have not said exactly how the children ended up in the water. But Detective Mary Wheat, spokeswoman for the Portland Police Bureau, said the Multnomah County district attorney's office was preparing for a grand jury hearing on the charges that was expected to begin Friday.
