Johnny Lee Johnson, the estranged husband of former Auburn woman Kimberly Johnson, was convicted of her murder in a one-day jury trial Wednesday.

Johnny Johnson, 43, of Coon Rapids, Iowa, was also convicted of murdering Gregory Allen White, 38, at his wife’s apartment in Bayard, Iowa, on April 29, 2007.

Kimberly Johnson, 37, was a native of Brunswick who had lived in Auburn and Mechanic Falls and graduated from the Bernard School of Hair Fashion in Lewiston. She met her husband while Johnny was serving in the Marine Corps about 20 years ago. They moved to the rural Coon Rapids, Iowa, area to raise their children, who are now teenagers. About a year before her death, Kimberly and their children had returned to Maine, but the family later reunited. Kimberly moved out of their family home and filed for divorce about a month before she was killed.

Police released few details of the crimes before trial, but during the trial neighbor David Halterman testified that he saw Johnny Johnson walk to the apartment door at 10:20 p.m. on April 29. Johnson apparently shot White twice in the back through the screen door while White stood in the kitchen with his back to the door, putting a container of ice cream back in the freezer after scooping some into a bowl.

Police and witness testimony revealed Johnny Johnson fired a third shot at White and then walked down the hall, entering a bedroom where Kimberly and Jessica Johnson, the couple’s teenage daughter, were located. He fired four shots at Kimberly before beating her and White in the head with his gun.

Jessica Johnson fled from the apartment and asked a neighbor to call police.

The murder weapon, a CZ52 7.62mm Tokarev, was recovered in a ditch on a road between Bayard and Coon Rapids, where Johnny Johnson still lived in the couple’s marital home.

According to police, Kimberly Johnson and White, who lived in the same apartment complex, had apparently started a personal relationship, which angered Johnny Johnson, just before the shootings.

Johnny Johnson turned himself in to Guthrie County authorities after the shooting, and has been held at the Guthrie County Jail on $2 million cash bail since then. He is scheduled to be sentenced Monday on two counts of murder in the first degree.

in a Guthrie County District Court.
