|Location||San Francisco, California|
Glen was Madison's next door neighbor. Glen was also a werewolf, and in this form, over the past year, he had been hunting prostitutes at Hunter's Point, killing several during that time period. A month prior to Sam and Dean Winchester coming to town, he had bitten his neighbor, Madison, turning her into a werewolf.
On the second night of Sam watching over Madison, Dean visited the area of town where the previous victims were attacked. Dean comes across Glen while he is staking out the location dragging a hooker away, when Dean catches up, he shoots Glen three times in the chest with silver bullets. While dying, Glen reverts back to his human form, realizing that he changed again, but nevertheless confused about what had just happened before he finally dies.
