Court documents said Moreno's mother called police after he called her saying "Mom, come down to the Portland bridge and get my phone and the stroller so you have pictures of the baby."
Before that, he reportedly got into a heated text exchange with the baby's mother where he told her "Enjoy your new life without us."
Tony Moreno then attempted to commit suicide on a Sunday night in July.
When officers arrived at the bridge, Moreno jumped off the Arrigoni Bridge before they could get to him. Police said Aaden was not with him when he jumped. There was an empty stroller located in the vicinity of where Moreno jumped.
According to documents, family members who arrived at the scene before Moreno jumped said they just couldn't stop him.
His mother told detectives "When Tony saw the police officer walking towards him, he started to walk towards the Portland side of the bridge. He started to pick up speed and then out of the corner of my eye I saw him leap over the railing and fall to the water. I immediately ran to the stroller to check the baby, but the baby was not in it."
All proceeds of the walk will go to New Horizons Domestic Violence Services.
