The release of fresh images of Fiona Anderson just hours before her death led to 13 people coming forward with information, Suffolk Police have said.
Witnesses say they saw Fiona walking in Lowestoft on the morning of April 15. This includes the cyclist, who was pictured cycling along Gordon Road at the time when Fiona was seen entering the car park.
The funeral service has been held in Lowestoft for three children killed by their mother, who then committed suicide.
The funerals have taken place for three young children killed by their mother in their home in Lowestoft in April.
The parents of Fiona Anderson reveal she left messages on the walls in an interview with broadcaster Fiona Phillips, on Daybreak.
