The warrant lays out Catroppa's alibi, which he provided to investigators during questioning.
Catroppa told police he left his Robinson apartment, picked up food to take to his mother's Aliquippa home and remained there until 4 p.m. From there, he went to his girlfriend's mother's home in Center and stayed there until after 5:30 p.m. He then returned to his mother's home to pick up food before returning to his apartment at the Ridge at Robinson.
He told investigators he was there with his girlfriend for the rest of the night, according to the warrant.
Investigators said in the warrant that Catroppa's key fob data showed no log-in times for his apartment or the building on May 13. They said no security cameras show his apartment, so they couldn't visually verify whether he had been there.
The search warrant, executed May 19, said some of DelTondo's family members and friends alleged that Catroppa and his friends and associates had been following DelTondo after she and Catroppa broke up.
