Basically there are seven unsolved cases from 1971 to 1989 of girls aged 13-18 seemingly abducted off the streets, sexually assaulted, murdered, and disposed of in the nearby desert. If we exclude the one from 1989 the range narrows to six cases from 1971 to 1983.
I have not looked at the individual cases very closely, so not sure how similar they look.
I think it's just a question of probability. How likely is it that some of these cases are due to the same perpetrator or perpetrators?
Arguments for:
+ It seems to be a relatively high number of victims of that sort of stranger abduction killing in a city in the 300k-500k range over a decade. These cases of school girls being snatched off a street, raped, and killed, if that's what these are, are very rare and get a lot of attention when they do happen.
Arguments against:
- The argument for is so obvious that maybe we should assume LE has reason to believe the various cases are not connected.
- It's not THAT many, active serial killers can easily generate one victim every few months. This is much less than one a year depending on how you parse it.
Other considerations:
+/- Are there any missing girls from the area as opposed to just found deceased that could be added to the tally?
+/- If the count seems suggestive but too low for an active killer, it's possible there are victims in another jurisdiction.

Her parents reported her missing at approximately 6:00 p.m. On December 31, 1983, at approximately 10:00 a.m., a construction worker reported a dead body in the desert area near Spring Mountain and Buffalo.
Diana was identified by her parents. An extensive investigation was undertaken. It appears that the suspect abducted Diana somewhere along her route and drove her to the area where she was discovered. Diana was sexually assaulted and murdered. There were signs of a struggle in the immediate area and Diana's clothing was located near by. In spite of the extensive investigation no viable suspects have been identified.

During this five year period (1979-1983) the population of Las Vegas grew from 413,000 to 525,000. Seems to me five girls aged 13-15 and one aged 18 being abducted and killed in that period is unusually high. Also the girls tend to resemble one another, judging from the pictures. All white, almost all brunettes. (I'm not including the outlier case I mention in these observations.)
