stolen 2008 Specialized S-Works Tarmac SL

Some time between 10pm on 6/12/21 and 5am on 6/13/2021 someone entered my basement through a side door and stole my road bicycle. Security cameras in the rear of the house did not detect anyone, security lights on the other side of the house did not detect anyone. No loud noises were heard, so someone probably climbed a locked gate at the side, or climbed the neighbor's fence and approached my closed basement door. Although the basement has much property in it, only the bicycle was stolen. The bicycle is a ~ 2010 Specialized S-Works Tarmac carbon frame road bicycle, black and blue in colour. With Mavic GP4 wheels, Shimano group set. It has a white Selle Extra saddle, and Easton black handlebar with white tape. No sign of forced entry so it's not clear if they picked a lock, or had a way to open the door without damaging it.
