Webster Gunman William Spengler Terrible at Repaying Favors

So how did convicted felon William Spengler acquire the guns with which he killed two firemen in Webster, New York, earlier this week? According to authorities, a young neighbor, 24-year-old Dawn Nguyen, bought two of them for him two years ago at a gun store. And they figured it out with a tip from Spengler himself:

The rambling letter Spengler left behind, which [U.S. Attorney William] Hochul described as a “suicide note,” informed authorities that the guns had come from the daughter of a neighbor.

We guess that crazed old man next door who murdered his grandmother with a hammer and wanted help buying guns illegally wasn't the most trustworthy guy after all.
