Mr Rowe, who relies on a gopher and crutches to get around, noticed a dozen cans of beer had gone missing from outside his home on Tarrawan Road, in Armadale, on Monday, April 14.
He replaced the beer, which was sitting on the porch outside, but the next day it went missing again.
On Wednesday, Mr Rowe decided not to leave the beer on the porch, which he assumed would stop the thieves.
However, while he was having a family lunch at the back of his home on Wednesday afternoon, his house was ransacked.
The thieves stole his wife’s handbag, which contained $150 cash, a $100 gift voucher, which has since been cashed, and two wallets.
They also took something of much more sentimental value, a polished wooden box, containing an old magnifying glass that belonged to the couple’s late son.
To make matters worse, they found their side gate smashed in on Thursday.
Mr Rowe said he and his wife, who have lived in the area for 38 years, were shocked by the incidents.
‘It’s not a nice feeling when you know someone’s been through your home,’ he said. ‘You sit there wondering when it’s going to happen next.’
Mr Rowe said the brazen thefts and vandalism should serve as a reminder to other residents about the need to keep their doors locked at all times.
‘They must have just walked in the front door, while we were having lunch out the back on Wednesday,’ he said.
Armadale police are investigating.
