Red pulsing light in Gilbert, Arizona

My sister had left my house, and was about a block away from our house when she noticed a red light, very bright, and pulsing, but more or less stationary, just above and to the north.  She and her husband drove back to my house to let us know about it, and my whole family watched it.  My oldest son was on the phone with a friend, who lives about a mile away, and he went outside with the phone and also seen it in the sky.  It was very bright red, almost like a lazer pointer color and brightness.  It would sit stationary for a while, then move slow either east, or north at times.  We watched it for about a half hour, and later that night, I watched the news, and it had been reported on Fox 10 news, they even showed video of it.  The news reported they contacted Williams Gateway Airport, and they said it was a cessna airplane, but no plane could sit stationary like it did. I called the news and told them we witnessed it, and there was no way it was a plane.
