The broken window was the most exposed to sight, the closest to the road and the most illuminated (as well as the less easy one to climb in).
I don't agree with you on that. And what may be "less easy" for you or Mignini or me is a "piece of cake" for Rudy.
To throw a rock through Filomena's window, Rudy stood at the car park area that protrudes from the side of the road. From that spot, he had to toss the 9 lb. rock horizontally 8' or so - something a basketball player could easily do. Before tossing it, he had to see if any pedestrians or cars were coming along the winding road. Several trees along his side of the road near the car park shielded him somewhat and gave him a feeling of being less noticeable. If he needed to escape, he could take off in several directions including jumping down and running down the hill through the trees and vegetation.
The window would have be difficult for Mignini to climb in. But Mignini at the time of the crime (Nov 2007) was 56 years old, 5'10", and about 210 lbs. Rudy at the time was about 21 years old. He was a trim, lanky basketball player who could bob, weave, spin around, duck, dribble a basketball, do jump shots, and maybe even "stuff" the basket. The window grid bars on the lower window are an inviting ladder to climb up. When standing on the window grid's top horizontal bar, Rudy would have been at chest level at Filomena's windowsill.
Those who suggest that the most logical entry route - through the doors on the terrace - are suggesting what
they prefer as the entry point - probably what they would chose if they had to do it. But Rudy had different criteria. Tossing the rock horizontally 8' from the car park was easy for Rudy. Standing at the car park area just off the side of the road partially shielded at night by roadside trees might have been comfortable for Rudy. Being able to choose your direction of escape from the car park may have been a comfort factor - that location afforded him
5 directions of escape - up the stairs to the basketball court he knew so well, 2 directions along the road, into the parking garage with its other exits, or jumping down and running downhill through the trees and thick vegetation. Lots of options from the car park area.
I will point out that anyone choosing to break in through the terrace must first get up to the terrace. Easy enough to do as the window on the wall beneath the terrace has horizontal window bars, just like the window beneath Filomena's window. In either case, climbing up the window's grid-like bars puts the climber in a standing position where he places he hands on the terrace edge or Filomena's windowsill and raises himself.
