I stumbled across this website, and this particular cold case, completely by accident. While I am not a crime sleuth, I do think I can provide information and clear up some misconceptions concerning the area in which the acccident occurred. I was raised in Houston not far from the accident site, and I was 20 years old and still living in that area at the time. Of course, it's been over 20 years now, but my memory of the area should still be fairly accurate. Please feel free to verify my recollections via
www.maps.google.com, as I believe their maps are much more accurate than mapquest. Not to mention that google has an option to view the map as a hybrid, with an aerial overlay, which will make this very helpful for getting an idea of the actual scene of the accident, IMHO.
First off, to clear up some previous misstatements within this thread. The University of Houston is neither close to either of the airports in Houston, nor the accident scene. Rather than being within a 5 to 10 mile (roundtrip I assume) bike ride, it is probably closer to about 20-25 miles one way. Factor in to the equation that Houston was always a dangerous place to ride bicycles and the thought of a leisurely ride from U of H is very unlikely. Being a former avid bicyclist myself, I know first hand how much vehicles hate the idea of sharing the road with a bicycle, and at that time in this particular area, sidewalks were very scarce. If it were a workout or training ride of 45-50 miles, I sincerely doubt an avid cyclist would be wearing Nike gym shorts and riding a Sears bicycle. Secondly, the scene of the accident is also nowhere near Spencer Highway. Spencer Highway runs through Pasadena in far southeast Houston, and this occurred in north Houston. Thirdly, the accident occurred on October 5, and any college in Houston would have started classes either in late August or early September. So I don't think it would have been a student taking a break from unpacking before classes started for the semester. Fourthly, George Bush Intercontinental (or IAH as it's still called by most people from Houston) has always served international flights. I remember flying from there to Spain on a school trip in the late 70s. It is true, however, that the accident site is very close to IAH.
An alternative, for those still pursuing this angle, is that she was a student at (what was then called) North Harris County College. NHCC is approximately 8 miles northeast of the accident site. While it would be easy enough from the campus to head south along Aldine-Westfield and then turn west on Rankin for a bike ride, it would still be unlikely given that both those roads were two-lane blacktops with neither shoulders nor sidewalks...only open ditches. Also both roads had speed limits of 45 MPH with most vehicles travelling faster than that. This part of Houston was still very much undeveloped at that time. You can see even now on the google map that this area is still heavily wooded. At that time (I don't know about now), NHCC was strictly a commuter college and had no student housing. Most of the students were either recent high school graduates who still lived at home or were adults taking continuing education courses. Either scenario lends itself to an assumption that someone, somewhere, would notice this young lady had disappeared.
Now on to a few key details. First, Rankin Road was known at that time as a place where young people (mostly high school students) would go hang out to drink beer and drag race. It was mostly an industrial area, so at night there was usually very little traffic, and the road was nice and straight. Unfortunately,the case history doesn't say what time of day this accident occurred. Secondly, if you look at the google map, you will notice one car dealership at the northeast corner of Rankin Road and Interstate 45, and another about 1000 feet east of the intersection along Rankin. Neither of those were there at this time. However, you will notice a development at the corner of Rankin and Rankin Circle West. That was there back then, and one of the establishments in that development was a gentleman's club.
I would be reluctant to bring up the possibility that she could have worked there, but it is an avenue that probably should have been explored. Can we make the assumption that there is a tendency for young ladies working in those establishments to have come from somewhere else? Maybe trying to escape from somewhere or somebody? I don't know anything about the hiring procedures for those types of businesses, but I imagine that there is a high turnover rate and an employee suddenly ceasing to appear for work might not raise a red flag. The accident site is just west of that development, and in that direction, west of Interstate 45, there were apartment complexes even back then which would be the closest housing of any type.
That is about all that I can add. I hope I provided meaningful information for somebody, somwhere. If there's one thing I'd like to point out, it's the importance of carrying identification even while riding your bicycle. As previously stated, I was once an avid cyclist, and I had a little pack that attached to my seat post in which I could carry a spare tube and a few bike tools. Even more importantly, I used it to carry my house key, my driver's license, and a $20 bill. While I was lucky enough to never have needed my driver's license, I made use of that $20 on one long weekend ride when I had not one but two flats. The second occurred when I was still about 10 miles from home but that didn't take too long sitting in the back of a cab thanks to the $20.
