Lucifer, Stay. Good Devil. - S1-E2
Continuity mistake: Chloe is being debriefed by her ex about the crime scene. There's a close-up of the photographer who will be the key of the case, being physically pushed away by a policeman. The scene goes on with him in the background in many shots, all on his own, snapping away as if nothing happened. (00:08:55)






Answer: Yes and no. After the body dies, it loses about 1.5°C per hour until it reaches ambient temperature (i.e. the temperature where the body is found). But there are factors affecting the rate of loss, and one has to assume a starting temperature of 98.6°F. In this case, after factoring in the time from when the police were called to when the body temperature was checked, it would have been determined some time had passed, just not a lot, before Beth saw Moira standing over Megan. Really, what they were saying is Moira's story is believable: that she found her sister dead and picked up the hammer right as the garage door opened.
