I believe he told them. So it would appear he didn't act for long as a grieving widower. Chad's brother statement says he found out Chad remarried from Chad's neighbor. So looks like people quickly knew Chad had remarried.Was Chad spending some of his unaccounted-for time back at the family home in Salem acting as though he was a grieving widower....and some of this timeframe at Lori's Rexburg townhome on a honeymoon?
(By the way, how DID the Daybell children find out about his hasty remarriage? Is this known?)
