Palm Beach County sheriff's authorities arrested Lisa Shannon on an attempted murder charge after the shooting at the Wellington-area home.

WELLINGTON — It was April 15, Tax Day, and though they were getting divorced, the Shannons still had to finalize the paperwork together.

The man arrived at the home they once shared east of Wellington, and tax discussions spiraled into divorce-fueled arguments about money and making repairs to the home.

Lisa Shannon snapped.

The 55-year-old told Palm Beach County sheriff's investigators she fired a gun "more than once" at Ralph Shannon, her husband since 2001, when he refused to leave. Neighbors, however, told authorities that the 61-year-old man already was on the driveway when she fired into his back and had collapsed before she fired the second.

"She shot me," he told a detective. "We (are) going through a divorce and she shot me."

Authorities arrested Shannon on an attempted first-degree murder charge. She is being held without bail at the Palm Beach County Jail.

A detective found the bloodied, screaming man outside the home on Hunting Trail south of Lake Worth Road shortly before 4:30 p.m. Monday. According to sheriff's records, he suffered multiple gunshot wounds and is in critical condition.

Neighbors told deputies the couple frequently argued and as recently as "a couple weeks ago" authorities were at their home for a dispute. Court records indicate that the couple was involved in a physical confrontation as far back as 2010.

Shannon described her husband of nearly two decades as controlling, manipulative and angry. Over the last eight years, the couple has struggled with finances, and in the last two, her husband increasingly distanced himself, she said.

Shannon told authorities they couldn't agree on how to fill out tax paperwork. That dispute turned to talk of their divorce. Shannon said her husband "was antagonizing her" by telling her things to fix before she sold the house. She said he chest-bumped her and she pushed him away by his neck and face.

He started to pick up his documents and apparently smirked as he did.

Shannon said she reached into an end table and grabbed a .38 revolver. She told him to leave, but he refused. He told her to fix the air-conditioning before selling the house "so that I can get my portion."

That's when Shannon snapped.

"I know I shot him more than once," she told investigators.

She told deputies she shot him inside of the home and he made it outside on his own while she called 911.

Neighbors, though, said they saw her shoot him in the driveway.
