The heartbroken Perth grandfather of a baby allegedly drowned by his father in Queensland has described Elijah Rainbow Fisher as "the precious son" his parents had long wanted.
Victor Bissett told the Courier-Mail newspaper that before his daughter Lauren Fisher joined the frantic search for her son on Saturday night she had called her mother Stephanie with the distressing news.
Mrs Fisher reportedly told her mother: "Elijah has drowned. I need you to come up now."
Elijah was Lauren and husband David Fisher's only son and the youngest of their five children.
He would have been seven months old today.
Instead, his family are struggling to comprehend his death and the allegation that Mr Fisher drowned him in a river south of Brisbane while taking him for a walk.
Mr Fisher allegedly took his son out of his pram and plunged 15m from a pedestrian bridge into the Logan River with Elijah in his arms about 6.45pm on Saturday.
Police claim that the 38-year-old swam to safety and walked 1km back to the family's Eagleby home to tell his wife and four daughters: "Elijah's drowned. Elijah's gone."
Mrs Fisher frantically called her mother in WA and authorities before rushing to the river to search for her little boy.
Family members said Mr Fisher had been "wailing and screaming" when the calls were made.
Mrs Fisher posted a farewell on Twitter: "I was so blessed to meet Elijah Rainbow. 26.11.11 - 23.06.12. I love you, little one. Go with God."
Mr Fisher was charged with murder on Saturday night. Police found the baby's body on Sunday morning on the riverbank about 1.5km downstream from the bridge.
Mr Bissett said everyone was "trying to come to understand" the tragedy. "He was an active child, much loved by his sisters," he said.
Mrs Fisher spent part of her childhood in West Africa where her parents, Christian missionaries, ran an evangelical publishing business. She met David Fisher in 1996 after she moved to Australia.
Mr Fisher has been remanded in custody.
