Lisa Kepler says she met 19-year-old Jeremey Lake at a homeless shelter in downtown Tulsa.
"My parents kicked me out a week ago," said Kepler.
Kepler said she met Lake at the shelter and the two began dating immediately.
On Tuesday night, she said her father, Shannon Kepler, a 24-year veteran of the Tulsa Police Department, found the two of them outside Lake's house.
"We were outside for five minutes and that's when my dad pulled up," she said. "There was no argument. I walked away and Jeremey introduced himself and my dad shot him."
