The evening of 5/30 the detective wanted to talk to Wendy about the sex abuse investigation. IIRC, it was not a planned visit. Imo, whatever details came from that visit put Wendy in CYA mode. Panic mode. Was Wendy told about more allegations or maybe even the Facebook exchanges with Brittney? At the same time Wendy was meeting with the detective, Donnie would have been picking up Brittney and headed to Styx.
Detective arrives and askes to talk to her and her husband. Donnie is not home so he proceeds with her. The det. indicates that he is investigating some allegations of possible crimes and her name has come up in the investigation. He will offer her an opportunity to explain why her name would come up and they would converse back and forth. He would ask her when her husband would be home and tell her that it is imperative that he speak with Donnie. She may have called Donnie while the det. is there and arrangments are made for Donnie to meet the det. the next day. The det. will not do anything at this point to tip his hand as to what he may know about the case. The det. will then leave and await Donnie the next day.
I believe when the detective left, Wendy freaked out. It is very likely the first person she called was Donnie, who would have been with Brittney. Wendy probably called Donnie to tell him he had to meet with LE the next day and found out he was with Brittney. This was an unexpected meeting the next day, not something that had been planned. Imo, the next 24 hours were crucial for the perps to get their stories straight. Very little time to prepare. I believe several heated conversations went down that evening. Since Brittney was hanging with Donnie she would have been right in the middle of it all. Donnie and Brittney did not know about the detective visit until after Brittney was already picked up. I personally believe they probably would not have planned to hang out if they had known.
I believe at some point Wendy, Donnie, Jennifer and Brittney were all together. Wendy had to meet with her husband before his meeting with LE and her best friend (charged with *advertiser censored*) accompanied her. I believe this is when Brittney was murdered. I don't believe it was planned because I don't believe Donnie would have went along with it. Wendy was likely in a very unstable frame of mind and maybe murdered Brittney in a rage fueled state. Did Donnie help hide the body, I don't know. But I believe he was struggling with keeping quiet and his wife sensed it. Hence one of the many reasons I believe he was murdered right before he was to meet with LE.
This is the critical point of the evening. With this pending meeting hanging over his head, what does Donnie do?
At this point he is supposedly alone with Brittney at his Styx River home.
Do they discuss it? Does he ask her what she knows about the case?
Are there any records of further phone calls from Wendy?
There is no indication that Donnie and Brittney went back to Tillmans according to cell pings.
What motive would Wendy have for killing Brittney?
The det. would never mention Brittney making any allegations against Wendy, while in her home.
What would have incited her rage then? (Assuming that is true).
Wendy's actions when she allegedly found her husband with a self inflicted gunshot wound were completely irrational. IIRC, she deleted messages on his phone before calling 911? There is something very wrong with that picture. There were several hours to think about eliminating Donnie after Brittney was murdered. Donnie cared for Brittney, however unusual their relationship may have been and I think Wendy had some jealousy issues. As well I think Donnie was killed for multiple reasons. One, hoping the investigation would end with his death. Two, he was a witness to Brittney's murder. Third, he was worth more dead than alive or in prison. All my opinion.
Wendy must have known there were some incriminating texts on his phone for her to have deleted them. Probably related to the incest case.
Was she protecting herself, the ultimate killer of Brittney, or Donnie?
Wasn't Brittney's gun used to kill Donnie?
Who would have known it was in the truck?
Self preservation is the strongest motivator to force one's hand.
There is a limit to what someone will do to protect someone else but no limit to protecting yourself.
