Kaylen Johnson was 24 and six months pregnant when she and her two-year-old son, Kaden, were reported missing after last being seen on March 5, 2022, in Baton Rouge, Louisiana. Their bodies were found on March 14 in separate locations. An autopsy showed Kaylen died from multiple gunshot wounds; the child’s cause of death was later reported as hypothermia.

Investigators focused on Kaylen’s boyfriend, Brynnen Murphy. He initially refused to cooperate, then turned himself in on March 14 and confessed to killing both Kaylen and her son. He told police he shot Kaylen in the parking lot of his apartment complex and afterward drove to a bridge and threw Kaden, who was still alive, over the side.

What details about Kaylen’s last day or the movements of those involved have not yet been made public that could help explain how this unfolded?
