I found this article quite interesting regarding the time of Mary's death
Rigor mortis has been reported to commence, under average conditions, within three to four hours after death, and will disappear at 36-48 hours after death; however, the exact period and duration is highly variable. The onset of rigor mortis does not follow a constant or symmetrical order; however, it will typically develop in smaller muscles first - in the eyelids, face, lower jaw and neck, before moving on to the trunk and limbs. There is no measurable shortening of muscles unless the muscles have been subjected to tension prior to onset. When rigor mortis is fully developed, the joints of the body become fixed, and repositioning of the limbs is only possible by brute force - once broken, the rigor will not return, provided it is fully developed. It is traditionally accepted that rigor mortis passes off in the same sequence it developed, to secondary muscle flaccidity.The period of development is influenced by factors such as:Temperature of the environment - High temperatures both accelerates the onset of rigor mortis and shortens its duration; if the temperature is below 10C, development of rigor mortis is considered rare.Muscular activity prior to death - It has been observed that rigor mortis develops and passes quickly in an individual who died after prolonged muscular activity.Disease and unnatural death - Septicaemia and wasting diseases hasten the onset of rigor mortis; death by asphyxia tends to delay it. Similarly, death that is preceded by severe haemorrhaging causes rigor mortis to develop late
All three of the factors mentioned delaying the onset of Rigor Mortis probably happened with MJK. So the likelihood that it was delayed from its usual onset of three to four hours is highly likely.
Ps Also read this in the same article - The greater the surface area exposed, the more quickly the body will cool Think it is fair to say with MJK

Do you have a link for that article?
I tend to collect pdf's concerning Time of Death, and causes.
There is a good one that describes what 19th century doctors used to help determine ToD - Algor mortis, Livor mortis, Rigor mortis, Decomposition, etc., plus Niderkorn's tables which were the standard for the time.
http://www.dumpio.fr/_media/time-of-death.pdf

What I have not been able to locate is a 19th century source which explains how Rigor mortise develops. I'm sure they were not aware it was due to chemical reaction.
I would like to know if they thought it was the result of temperature, but I just don't know.

C 1881, Kuhne suggested Rigor was caused by a chemical act involving myosin. I'm not sure if he had it exactly, but was he along the right lines?

Point of interest that Eddowes had connections to Yarmouth .Eldest was born there .
Another one of those oddities ....

There are many coincidences in Jack the Ripper's story.

Some are simply that,some really add up.

There was a rumor that Eddowes had, at one stage, slept in Dorset Street.
I suspect she returned from Kent a day or two before recorded.

Yep .... she slept at ' the warehouse '
26 Dorset Street
Yep , admittedly the yarmouth link almost certainly would be coincidence ....many other incidents are not

Think it was a residency built over stables, next door to Millers Court.

Yes, myosin fibers.
I've also seen is suggested that the cramp we get periodically, which is due in part to a buildup of lactic acid, also is a contributing factor in Rigor Mortis.
There are contesting opinions on this.
