In 1987 the owner of the Wax Museum in Grand Prairie was murdered in
her home. It's to bad that no one cares. Does anyone have any infomation
about this.

There is so little information on this case.
The closest I found was on this website that features paranormal investigations in North Texas.

Grand Prairie - Tarrant County - Palace of Wax/Ripley's Believe It Or Not

Description:
601 East Safari Parkway North of I-30 & West of N Beltline Rd on E Safari Pkwy

Victims of a fire are believed to haunt this museum. There are strange presences felt, and electrical malfunctions that cannot be explained. There are also strange noises like bells and the sound of someone screaming. There are stories of the motion detectors going off when no one was in the building except for a few staff membe
Even though there was no one killed in the fire itself, the event is surrounded in mystery since one of the owners was murdered a year before the fire. Her name was Patsy Wright and she was poisoned with strychnine that was put into some medicine she was taking. Three years before that, in 1984, Patsy's manager and director of marketing at the wax museum, Lori Ann Williams, died mysteriously. Both bodies were later exhumed to determine the cause of death and to see if the deaths were related. These poisons evidently don't show up without a urine test. The results were inconclusive. There is a lot more mystery there than can be imagined. Another event occurred just after the fire when a man, Stanley Lester Poyner, was caught stealing a ledger book from the rubble. He had been previously arrested for arson, and was later shot and killed by Dallas Police in 1991. Lots of murder and intrigue are associated with this one and I suppose quite a few spirits are looking closure or justice or both.

Here's an old thread with some more info on the case:

I think I speak for everyone here when I say that we would very much like to see Patsy's killer brought to justice.

Yes, I agree with wiseguy, we all at the board hope Patsy's killer or killers gets brought to justice. It does not matter how much time has passed by since the killing we all went justice for Patsy and her family. It is tough to say who did this one, obviously someone close to Patsy, someone who knew her well. I am sure the cops know who this person is they simpy do not have the evidence to charge them.
