That's actually not true according to FBI statistics. Just quickly according to 2005 data, of 14,860 murder victims only 2070 (14%) were strangers, as compared with 2436 (16%) who were either related or boyfriend/girlfriend. That leaves 3630 (24%) who were friends, acquaintances, neighbors, or employers/employees, or a full 40% who knew their victim personally.
The remaining 6724 (45%) are those for whom the relationship data were not available for this analysis, and naturally a big proportion of those would also be situations in which murderer/victim knew one another.
Now, you said "don't know one another well", and the FBI doesn't qualify the "well" aspect of it. But one theme that's clear is that murder is NOT random, it mostly happens among people who know one another to begin with.
