Yes, I'm going by the original timeline posted in the timeline thread.

Wednesday, Dec 18:
1:35am: SM called Heather from a
pay phone on
10th Avenue North; the call lasted 4.83 minutes
1:44am: From her apartment, Heather
called her roommate BW, who was in Florida, and spoke for 2.2 minutes; was
crying and upset after the call from SM
because she was trying to get her life back together after her affair with him and harassment by TM
1:53-2:09am: Ten posts were made to Heather's Tumblr
2:29am: Heather
tried to call SM back at the pay phone number several times, but no one answered
3:16am: Heather
tried to call SM's cell phone, no answer
3:17am: Heather
called SM's cell phone and spoke with someone for 4.15 minutes; Heather's and SM's phones were each at their own homes at this point

I believe you are basing your theory on the murder being planned before Sidney placed the payphone call at 1:35. Have you considered the murder may have been planned after that time? You are also basing your theory on a stalking scenario. My explanation of why Sidney failed to take advantage of Heather being alone in the apt. is not based on that theory. To the best of my knowledge, LE has never stated stalking is a part of their theory nor have they ever stated Heather was not in control of her phone before she was murdered. They have also never stated what time they believe Heather was lured out of her apt. Have you considered the murder was planned at some point after the payphone call at 1:35? Have you considered the plan to meet at PTL was first discussed shortly before Heather left for PTL at 3:21. Have you considered the communications via social media. LE is confident Heather drove herself to PTL? All that said, I cannot say LE's version of their PTL theory is no longer valid.
