Police said an argument occurred between Lake and Shannon Kepler, who was in a black Chevrolet Suburban. Lake, who reportedly was with Kepler's daughter, was shot "two or three times" after he told Kepler that he was her boyfriend, according to an arrest report.

Lisa Kepler, the 18-year-old daughter of Shannon and Gina Kepler, spoke with the Tulsa World on Wednesday morning from the front porch of the home she shared with the homicide victim, who also was her boyfriend.

Lisa Kepler and Lake were walking back from Guthrie Green and were in the street in front of their home when a black SUV pulled up, and Shannon Kepler stepped out.

Lisa Kepler said her father shouted at her and that as Lake attempted to introduce himself, Shannon Kepler shot Lake.

Lisa Kepler said she had attempted to stop the shooting but then ran and hid behind a large rose bush in the front yard as her father fired a shot at her that missed. Lisa Kepler said she told authorities it was her dad who was the triggerman.

"I'm not scared of my dad," she said, in tears and openly wondering why he would shoot someone he didn't know.

Josh Mills, 23, a friend of Lake's, said he was also at the scene during the shooting. He said Shannon Kepler also fired a shot at Lake's 13-year-old brother, who was sitting on the front porch. The bullet ricocheted and grazed the boy in the upper arm, Mills said.

Mills said he had paramedic training and tried to stem Lake's bleeding and locate the bullet wounds. Mills said it appeared Lake had been shot in the chest and neck from about 3-feet away. Mills and Lake hadn't known each other long but had become close.

"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. Lisa Kepler declined to say what those life decisions were.

"I really hope they rot in prison for a very long time," Lisa Kepler said of her parents.

A neighbor of the Kepler family, who wished not to be identified, said the husband and wife are "wonderful neighbors." She said the parents had "given and given" to their three daughters.

Friends and neighbors said the couple had adopted Lisa Kepler and her two siblings several years ago.

"They've done everything in the world for (Lisa)," the neighbor said.

She said Shannon and Gina Kepler were the type of neighbors who would shovel sidewalks or bring food over.

A second neighbor, who also asked for anonymity, said he was "tickled to death" two police officers lived nearby because it made the neighborhood feel secure. The neighbor said he didn't have a lot of interaction with the Keplers, whom he called "the perfect neighbors," but that Gina Kepler sometimes would stop in her patrol car and say hi to him.

"The whole neighborhood — it's unbelievable," the neighbor said when asked if he was surprised by the turn of events.

Lisa Kepler said the Day Center is where she met Lake, who offered to let her live with himself and his aunt, Pam Wilkins, within the past week. She said Lake was a sweet man and had been nothing but good to her since they had met.

Sandra Lewis, executive director of the Day Center, said Lake had never been a volunteer or employee with, nor a client of the center.

Lewis said she knew of Lake and that he "came around" sometimes. There weren't any incident reports involving him, she said. Lake would help carry in donations or pick up trash.

"He was always very helpful," Lewis said.

Wilkins, 50, said Lake had "a lot of love" for people, including those in the homeless community. She said her nephew was "the life of the party."

"No matter if we argued, he never let a day go by without saying, 'I love you,'" Wilkins said.
