Bicycle detail

I arrived home from my place of work on my bike Friday evening May 14th and parked it on our back patio alongside my wife's bike. This morning my wife worked in the garden and does not remember if the bikes were present but believes they were not. We realized at 8pm Saturday May 15th that the bikes were missing from our patio where I last saw both of them. Both bikes are steel frame road bikes, size 54cm. One is black with bullhorn style handlebars and white cork handlebar tape, with a white leather origin8 brand saddle and a large number of stickers on the frame. It has holdfast footstraps on flat, BMX-style pedals. The other is a light blue road bike with a brown leather Origin8 brand saddle. It has flat handlebars with rubber grips. It also has a black metal panier rack above the back wheel.
