Lax is my old home town, and I still work there. The problem is the deaths of a number of male, college students who are getting stinking drunk at downtown bars just a few blocks form the Mississippi, getting disoriented, staggering down to Riverside Park, and falling into the river. Once in the river, especially this time of year, it's difficult to get out alive. There is NO!! serial killer.
I live in a College Town with a large river running through the town. Some of the most popular places college students drink is about 8 blocks or less from the river. Yet I have never read of some college student getting drunk and "falling in the river" and drowning.
