Within twenty minutes, local police officers arrived at the luxury Dallas home to investigate the situation.
Mark explained the terrible event while holding Clara securely on his lap in the private study.
Victoria remained upstairs in the master bedroom, refusing to open the locked door for the officers.
She claimed through the heavy wooden door that Elena had simply tripped while holding the child.
Victoria accused Elena of making up a lie to cover up her own foolish physical negligence.
The lead police officer asked Mark if the suburban home had any security cameras installed inside.
Mark remembered he had installed subtle modern motion cameras near the high stair landing last month.
He opened his digital phone app and accessed the encrypted cloud video storage records instantly together.
The officer and Mark watched the clear high-definition footage on the small glass phone screen carefully.
The video clearly showed Victoria intentionally placing her hand on Clara's back and pushing her forward.
It showed Elena diving bravely across the hard floor to catch the falling child in time.
Mark closed his eyes as cold tears of pure betrayal leaked down his flushed anger-reddened face.
He handed the mobile phone to the police officer, who nodded with a grim serious expression.
The officers went upstairs immediately and used a master key to open the bedroom door lock.
They placed Victoria under formal arrest for child endangerment and criminal reckless assault charges today.
Victoria screamed loudly as she was led down the grand staircase in stainless steel police handcuffs.
She glared at Elena with intense hatred as the officers escorted her through the front door.
Elena sat quietly on the sofa, holding a warm blanket around her bruised physical shoulders tightly.
Mark walked over to Elena, his face full of heavy remorse and deep immense professional gratitude.
You saved my daughter's life today, Mark said, his voice trembling with real honest emotion.
