David connected the memory drive to his laptop inside his work van park nearby.
The encrypted video files began downloading line by line onto the bright screen.
Chloe watched the live progress bar with her heart pounding hard in her chest.
While waiting for the video to load, David ran a background search on Brenda.
They discovered that Brenda had used a fake identity to get hired at the estate.
Her real name was Brenda Vance, and she had a history of blackmail schemes.
She was actually working together with Mark's bitter ex-wife to destroy his life.
The ex-wife wanted to regain full custody of Leo to control the trust fund.
Brenda was promised a massive payout if she managed to get Chloe framed and removed.
The file download reached one hundred percent and the high-definition video started playing.
The camera angle showed the top of the grand staircase with absolute crystal clarity.
Chloe watched the video footage from earlier that morning with breathless shock and horror.
The video clearly showed Brenda sneaking up behind the stroller while Chloe was turned around.
Brenda reached out her hand and deliberately unlocked the safety brake on the rear wheels.
Then the nanny gave the stroller a subtle, deliberate push toward the edge of the stairs.
Chloe had tried desperately to save the baby, exactly as she had original stated.
The footage proved beyond any doubt that Chloe was completely innocent of the crime.
It also showed Brenda dropping to the floor and putting on a fake performance.
Chloe burst into tears of relief as she watched the undeniable video evidence play.
David saved three copies of the video file on separate secure flash drives.
They knew they had to return to the estate before Mark signed the legal papers.
Chloe called the local police precinct to report the child endangerment attempt immediately.
Two police cruisers agreed to meet them outside the grand mansion iron gates.
The time had come to face Mark and bring the evil nanny to justice.
