SALT LAKE CITY — Five people, including four members of the same family, were charged in Duchesne County on Monday with attempted aggravated murder for allegedly attacking a woman with a baseball bat and severely beating her husband.

Thomas Neil Tuinman, 35; Michael Wallace Tuinman, 30; Samantha Tuinman, 30; Stephanie Ann Tuinman, 33; and Byron Rashad Thompson, 29, were each charged in 8th District Court with attempted aggravated murder, aggravated assault, and aggravated burglary, all first-degree felonies.

The Duchesne County Sheriff's Office is investigating a motive for the attack, a statement released Monday indicated.

According to a Duchesne County Jail booking report, sheriff's deputies were called Friday to 2725 W. 2500 South in the Vaughnsville area.

"When I arrived I saw a woman sitting on the porch next door to this address surrounded by a few other people and she was screaming in pain," the officer wrote in the report.

The woman, who was bleeding from her head, nose and mouth, said that "somebody had broken their front door and beat them up," the report states.

Next door, a man was found bleeding from his head, nose and mouth, and had other cuts and bruises on his body, according to the report.

"He said that somebody had broken his front door and chased him and his wife outside and then hit and kicked him in the backyard," the report states. The man reported he had been beaten "with pieces of wood and other objects from his backyard and had also been punched and kicked while he was on the ground behind his house," the report states.

The woman said one of her alleged attackers "hit her with a bat in the head," according to the jail report.

Doctors discovered the woman had bleeding on her brain. She was flown by medical helicopter to another hospital with "extensive injuries," the report states.
