'Possibly more victims of Jason Lawrance'published at 14:09
Detective Chief Inspector Allison Rigby, from Derbyshire Police, said the trial had been devastating for the victims.
She said: "He seems to have targeted females who are divorced and widowed.
"Only Jason Lawrance will know how many people he has sexually assaulted - it is possible that there are other people out there.
"I just hope once this case is finished, they can move forward and start to rebuild their lives."
