Detectives are investigating whether human remains found in woodland could be those of murdered student midwife Joy Morgan.
The 20-year-old was killed in December 2018 by Shohfah-El Israel, who she met at the Israel United In Christ church in Ilford, east London.
He was found guilty of her murder and jailed for a minimum of 17 years in August, but her body remained missing.
Hertfordshire Police said officers had been called to a suspected human body found in woodland in Chadwell Road, Stevenage.
No identification has yet been made.
