DETROIT -- The family of the man allegedly killed while relieving himself on the property of a business on Detroit’s east side speaks out.

Mildred Johnson held back tears as she spoke about the incident.

Johnson said she and her husband, Shawn, were walking home Tuesday evening around 7:30 p.m. after being ticketed for driving with a flat tire.

They were on Gratiot Avenue and near their home when, Johnson said, her husband had to urinate and couldn’t wait.

Shawn Johnson went to the side of Asian Fisheries. While he was relieving himself, the owner of the store, Leroy Moon, came outside.

“He said, 'Get off my property, get off my property. You're not about to pee on my property,'” Johnson said.

Detroit police said Moon retrieved a gun, possibly from a friend, and shot Johnson.

Johnson said seconds after shots were fired 36-year-old Shawn Johnson was dead.

Moon, 69, was charged Thursday by the Wayne County Prosecutor's office. Moon was charged with first-degree murder, which carries a penalty of life in prison without parole. He was also charged with felon firearm posession and felonious assault.

Nearby business owners are shocked. One person said Moon is "too nice of a guy." He believed there was more to the story.

Shawn Johnson’s widow disagrees. She believes the incident was a clear-cut case that’s heartbreaking.

"It was senseless and sad that he had to take his life because he (expletive) on his property. That's the bottom line," said Johnson.

Johnson said she and her husband would have celebrated their fourth wedding anniversary this week and now she’s planning his funeral.
