Martin knew enough about construction to manage basic projects.
But he wasn't qualified to approve unauthorized wastewater connections or alter public infrastructure outside the necessary permitting process.
He hired a plumbing subcontractor and described the work as a temporary emergency arrangement.
The subcontractor, Tomas Rivera, later told investigators that he'd been asked to install limited temporary equipment while the permanent connection was repaired.
He believed an authorized repair would follow.
But when he returned weeks later, he discovered that the temporary arrangement was still being used.
He raised concerns.
Martin told him the issue had been resolved through association management.
Tomas requested written confirmation.
He didn't receive it.
Eventually, he refused to perform further work and documented his concerns in writing.
His records became important.
Not because they established everything that later happened.
But because they showed that the people managing the renovation had been warned the arrangement was not an appropriate permanent solution.
Cynthia had also received those warnings.
Emails recovered during the investigation described the need for a properly approved sanitary connection.
One contractor estimated the work would cost tens of thousands of dollars after restoration of the affected paving and landscaping.
Cynthia rejected the estimate.
Her message was blunt.
There must be a less disruptive way to handle this. I'm not destroying my courtyard for a plumbing problem.
Martin responded that a temporary pump arrangement could remain operational for a limited period while the permanent project was organized.
But the permanent project was never completed.
Instead, wastewater from the guesthouse continued moving through an unauthorized arrangement that investigators ultimately traced toward stormwater infrastructure.
During periods of heavier use, the problem became more noticeable.
The drainage corridor developed odors.
Unexplained moisture appeared.
And contaminated water reached the creek.
Cynthia knew enough to recognize the risk.
But she treated the problem primarily as an inconvenience.
Not a reason to correct the system.
Then Andre Walker moved next door.
A civil engineer.
A homeowner who understood drainage plans.
And a man who refused to sign a vaguely worded agreement allowing unexplained utility work along his pool deck.
That changed everything.
Cynthia had hoped to shift access and maintenance responsibility toward the neighboring property.
If Andre signed the agreement, she believed she could create a paper trail describing future work as association drainage maintenance.
That might have made it easier to conceal the distinction between a private sanitary problem and legitimate common-area infrastructure work.
Andre refused.
He requested plans.
Asked questions.
And eventually contacted the city.
To Cynthia, those were not the actions of a responsible homeowner.
They were threats.
