Constant hot red wire at light switch

So I removed a fluorescent light from my kitchen and noticed a RED wire was used as the hot wire to the light and a total of 3 bundles came together at the box with all black tied together and white tied together. At the switch, the red is attached at the top end of the switch but stays hot whether switch is on or off???? Even when the red wire is removed from the switch it remains hot. There is 3 switches in a row and only one is a three way, which is in the garage. Home Depot guy seemed stumped and I have no idea how this light was functioning in this fashion. Where does the constant power come from and is this wired correctly?? Any help is appreciated.

Welcome to the forums!

What meter did you use to determine that that wire always has power on it?

Yes. A single pole switch which apparently controlled the red wire but I don't see how since it stays hot.

I believe there used to be a 3 way switch for this light. We removed some walls and had the electrical fixed back then. Either way, it seems that the RED wire would become absolete.

I'm just a little confused. You have a wall switch that controls a fluorescent ceiling light.
Now you are changing the fluorescent light.
Did you have a problem with the switch operating the light ?
Did you check for power AT the light ?

You can't use a pen A/C indicator because all that pen is telling you is
Danger.......hi voltage ac present.
That's its job. That's all it's supposed to do. You cant use it to figure out which wire inside a box is live. As long as the wires are near each other or cross each other....they can all check as hot.

Update: The wire is not hot. Pen detector just very sensitive I guess. Used volt meter to check. False alarm.
