A clearer picture of mom's involvement:
"Police were asked to make a welfare check on Noah by his mother Jillian Marie Godfrey, on March 12, according to the declaration.
She originally told officers she last saw Noah when she dropped him off March 4 at Bryce McIntosh’s apartment in the 4600 block of Temescal Valley Road in Corona. But she told detectives March 13 she actually last saw the boy on March 2, during her March 1-3 stay over at the apartment.
She last saw Noah, she told detectives, when Bryce took the boy into the bathroom.
While Noah was in the bathroom she said she heard Noah ask Bryce why he was hurting him. Jillian said when she left Sunday, Noah had still not come out of the bathroom, according to the declaration.
A warrant search of Jillian Godfrey’s phone “showed notes where Jillian was documenting Bryce abusing Noah,” the declaration said.
The evidence leaves no doubt that Noah was a victim of a homicide, Corona Police Chief George Johnstone said at the Thursday morning news conference to announce that the murder charge had been filed."
