Since the death of Marg Allerston-Medeiros’s mother in April at the age of 86, someone has been stealing mementoes, flowers and other items from the grave. Flower thefts had been going on for over 3 months.Allerston-Medeiros set up a secret camera in the cemetery and caught a slim, blonde woman who looks to be in her 20s stealing flowers from the grave.The woman and police in London, Ont., are asking for the public’s help in identifying the suspect, who appears to be smiling as she runs off with her gravestone haul.UPDATE:Fed up by the thefts that began after her mother Alma Allerston was buried in April, Medeiros installed a camera on the branch of a nearby tree on Wednesday.The camera recorded a female wearing a hoodie and shorts ripping flowers in front of the gravestone out of the ground and putting them in a cardboard box. The woman, who appears to be in her 20s, then runs away.Meideiros turned the video over to police and filed a report on the theft. She estimates it’s the 16th time her mom’s grave has been stripped bare.
