Emil Jennings was the son of Einer Jennings, and the father of Hank Jennings. He was married to Jolene.[1]
In his school years, he was a classmate of Douglas Milford, who would later remember him as an old friend.[1]
As an adult, Jennings was a man of ill repute in the community of Twin Peaks, infamous for being a serial offender, who had already built up something of rap sheet of petty crimes at a young age, and a notorious drunk, who owed money to many people in the town. His bad reputation also spilled over to his son.[1]
Emil died in 1964, when he passed out drunk in his basement and landed in the tub of the beer brewing apparatus he had stashed there, drowning in his stupor.[1]
