The man police want to question.
A tin of cash donations meant to go towards a memorial plaque for slain Bacchus Marsh woman Sarah Cafferkey has been stolen.
Police believe the tin was taken from the FoodWorks supermarket in Bacchus Marsh on Monday morning.
Officers were called to the supermarket about 2pm on Tuesday after the tin was noticed to be missing from near a register.
A police spokeswoman said CCTV footage suggested the thief stole it about 10.30am on Monday.
An image of the suspect has been posted on Facebook. He is of Caucasian appearance, and wearing a black hat, blue shirt and a white striped jumper.
Ms Cafferkey, 22, disappeared in November and her body was found days later discarded in a wheelie bin at a home in Point Cook. Police have charged a man with her murder.
FoodWorks manager Michael Harkom said some staff members had known Ms Cafferkey and he was disgusted the money tin had been taken.
He said about $200 would have been inside the tin, which was half full.
‘‘It’s just disrespectful, it’s like stealing money from the dead really,’’ Mr Harkom said.
