Kepler was dating Lake, and her parents, both Tulsa police officers, have been arrested in connection with the fatal shooting.
"He was like a brother to me for two weeks," Mills said, tearing up as he described how Lake died in his arms.
Lisa Kepler said her parents had kicked her out of their home recently because of poor "life decisions" she had made and dropped her off at the Tulsa Day Center for the Homeless.
Josh Mills, 23, a friend of Lake's, said he was also at the scene during the shooting.
Both are held at the Tulsa jail, police chief Chuck Jordan said, but are confined in an area away from other inmates they may have come into contact with on the job.
