Any good detective like people who can help come to a realiatic conclusion of this crazy thing that happened?

No name calling/ bashing/ derogatory comments please.

8 year affair and now this Bizarre thing happened who is a good detective?

My APs wife and kids go to his side apartment in another state once a year.
They were there for a week and left 2 days ago. The day they left the housekeeper came.

This apartment he leaves the side door unlocked like an idiot because he says thers nothing to steak.

There is a weird isolated married blonde tenant in the house and a brunette housekeeper that has access every week.

This morning my AP lost his mind.
He Said his hair brush was turned over and big blob of my blonde hair was left on top of the brush. He asked if I went into his apartment snooping when he wasn't there last night! It was not me!

It's a very hidden house. I'm thinking it's either the housekeeper, but why would she come back the next day and do that?
The upstairs neighbor knows something is going on and did that maybe using her own hair because she saw his family there?

Or his wife n kids found a brush or vacuumed or something and found my hair?
Then told a friend to do that as a mind fuck?
( We cleaned up real good though )

He's so upset he cancelled our plans this evening because he said he's not in a right way over this. His stomach is bothering him and his nerves are shot.

Was it a psycho way to break plans so I wouldn't be very mad?

I asked to see the hair. He said he threw it in the garbage. I asked to see the garbage. He Said he threw it all out because of the smell and it attracts raccoons. Which it does. I asked him to go get it he Said he many he threw it away at the car wash he went this am.

He throws his garbage out everyday.

Thoughts on this outrageous situation?

The most realistic thing I can think pf is his psycho 18 year old daughter had her friend do it.
Because they know he's cheating but aren't allowed to confront him.
