I believe she was "spiking" his drinks over several months. He did seek medical treatment in the spring but nothing was found-he just didn't
feel good.
Then he suspected his wife of trying to poison him. Once he captured the first video he drank nothing else and capture 3(?) more of her using the Drano.
He does have some internal injuries but is expected to heal.
This is not the first time somebody poisoned a significant other-a little at a time can escape detection but the accumulation in the person's system can go undetected until the major damage/death has happened.
