Diann revealed she and Frank were engaged in 2017 and were living together in his Iowa farmhouse.

In November 2018, she “walked in and caught him in bed with another woman.”

After the two reconciled, she claimed an incident took place at the farmhouse when Frank and a friend set off fireworks.

Diann claimed the men “had been drinking” at the time, as she went into the home while they lit the fireworks.

She continued in the court papers that the men were unable to light a firework.

Diann alleged: “Both defendants then put it in a closed cylinder vintage ashtray and tried to light it there. The firework did not light again and the Defendant just left it in the covered intake ashtray instead of properly disposing the firework.”

She then claimed that she wasn’t warned about the ashtray, as she used it while smoking a cigarette.

The lawsuit continued to claim: “The ashtray blew up severely burning her hand and arm with third degree burns and burnt off eyelashes and eyebrows.”

She claimed Frank “refused” to “take her to the hospital” and instead told her to “toughen up.”

She went to the hospital in the following days and was “treated for third degree burns.”

When the couple split again, she claimed he had the locks changed on a separate Iowa home they shared.

Diann demanded $50,000, claiming Frank was “negligent in the operation of fireworks.”
