Body of Abdul Ezedi, 35, is believed to have been found in the River Thames. He is suspected of spraying his ex-partner and her two young daughters with a chemical.
The woman, 31, was seriously injured and could lose the use of her right eye. The mother's condition has improved and she is no longer sedated, police said on Tuesday. Police said it would take time to formally identify the body, which had deteriorated and required DNA or dental prints. The suspect was previously convicted in 2018 of a sexual offense.
