The silver canister was preserved as relevant evidence.
Its visible identification markings were documented.
And the available camera footage was secured.
Andre provided statements describing what he personally witnessed.
He explained the history of the HOA dispute, the proposed management agreement, and the threats he'd received.
The officers also obtained information about the recorded video conference.
Ruth and the other directors confirmed that they'd witnessed Cynthia pouring the liquid.
The recording didn't require anyone to speculate about whether the act occurred.
It showed the woman entering the yard, approaching the pool, and deliberately emptying part of the canister into the water.
Elias supplied relevant professional information through the proper channels.
He didn't declare the substance identified merely because he recognized the container series.
He understood that labels could be altered and contents could differ from packaging.
But he explained why the source and handling history needed to be investigated.
That distinction mattered.
The response required qualified testing, not confident guesses.
Andre appreciated it.
He had spent years teaching clients that engineering conclusions needed evidence.
Now those same principles were protecting his home.
Cynthia's husband arrived shortly before sunset.
He was fifty-eight, a regional sales executive named Richard Vale, and he'd been married to Cynthia for twenty-six years.
He knew she'd been arguing with Andre.
He knew the pool program had become contentious.
But he hadn't understood how deeply the dispute was affecting her judgment.
When he saw the police vehicles and the restricted pool area, he looked stunned.
He approached the responding officer and identified himself.
After receiving an explanation of the situation, he turned toward Cynthia.
"What did you do?"
She began crying.
For a moment, he looked relieved that she wasn't injured.
Then he noticed the silver canister being handled by qualified personnel.
His expression changed.
"You brought that here?"
Cynthia wiped her eyes.
"I was trying to prove something."
Richard stared.
"With a chemical container?"
She shook her head.
"Andre made everything impossible."
Her husband looked toward the homeowner.
Andre stood beside his patio in the same yellow towel he'd been wearing when the incident began.
He looked exhausted.
Richard turned back to his wife.
"Did he ask you to come here?"
"No."
"Did he give you permission to put something in his pool?"
She didn't answer.
Richard closed his eyes.
For several seconds, he seemed unable to speak.
Then he whispered.
"Cynthia, what were you thinking?"
Her shoulders began shaking.
But Richard didn't immediately tell her everything would be fine.
He couldn't.
Nobody yet knew exactly what she'd poured into the pool.
