I get so tired of this.
Marital relationships are complex. Divorces are often complex. The truth is, all you know about this family is what you've read in the newspaper or seen on TV (reporters aren't known for 100% accuracy), and you've swallowed every word hook, line, and sinker. You don't know everything that went down, and you never will.
Don't let that stop you from calling people you don't know tramps, though.
