I've been going back and re-examining the timeline. Timeline states suspect in police gear was captured on surveillance video at 3:50 a.m. Missy enters the church at 4:20 a.m. Participant in her class arrives in parking lot at 4:35 a.m. 9-1-1 calls are made at 5:00 a.m.
However, paperwork from the police department states that Missy was setting up her room for the boot camp for "about 30 minutes," at which time she then heads towards where the suspect is waiting. Neither is seen on tape again. If this is accurate, that would mean she entered the building at 4:20 but did not head towards the suspect until 4:50 a.m. That gives the murderer only 10 minutes to murder her and escape before her body is found at 5:00 a.m.

MPD presser 4-18-2016 (in the media thread):
Captain John Spann: Like Chief said, we have some video surveillance.
The video in the church is works on motion section [sic], so we can't say
for sure when he got into the building, but he the first time he appears
on the camera is about ten minutes before 4:00 A.M. But that's not to say
that he wasn't in the building prior to that, because he may not have been
anywhere where they captured video.

Female Reporter: But do you know if it was if it happened very quickly,
if she arrived and
?
Captain John Spann: Pretty quick after she got there. Again, the timeline
from the boot camp members that were arriving there again, we know
the time that she entered the church, which I believe is going to be around
4:18 [A.M.], again, approximate time. We see her in the video. She's
walking down the main hallway in the vicinity of where we located her, but
when she gets out of the range of the camera it doesn't pick up the motion,
and the camera turns off, so we don't have anything. Like I said, we have
no video of the assault actually taking place.
MPD presser 4-22-2016 (in the media thread):
Assistant Chief Kevin Johnson:The suspect arrived at the church first and forced entry into the location.
Missy arrived a few minutes later excuse me, [the] first time surveillance
captured the suspect on video was about ten minutes before 4:00 A.M. Ms.
Bevers arrived at about 4:16 A.M. in the parking lot and entered the church
immediately. A few minutes later, she was inside the church, not realizing
the intruder was already inside, and shortly thereafter she was murdered
inside of the church. We're not going to discuss the details of how Ms.
Bevers was murdered. Our communications center received some calls to
911 at about 5:00 A.M. reporting the incident to Midlothian Police
Department.
