A Magistrates Court committal hearing for Sica, 39, was shown a police video of the accused killer being led on a "walk-through" of a crime scene where he discovered the dead children's bodies in 2003.
A visibly shaken Sica, wearing anti-contaminate suit and plastic shoe coverings to preserve forensic evidence, retraces his movements through the Bridgeman Downs home for detectives.
"I come up the stairs and I noticed a blood trail," he said.
Sica then declines to enter his former girlfriend's bedroom before telling them Neelma's mobile phone is not in its usual location.
