An adult man, an adult woman, a teenage girl and a very young boy are dead in what Mapleton police say may be a murder-suicide.

The individuals were identified Friday afternoon by the Mapleton Police Department as Timothy Griffith, 45; Jessica Griffith, 42; Samantha Badel, 16; and Alexendre Griffith, 5.

Badel is the daughter of Jessica Griffith, and the stepdaughter of Timothy Griffith. She was a sophomore at Maple Mountain High School. Alexendre is the biological son of both Jessica Griffith and Timothy Griffith, according to a Facebook post from Mapleton Police Chief John Jackson on Friday afternoon.

Jackson said in the post that the family had moved to Mapleton from Switzerland around July of this year when Timothy Griffith gained employment in the area.

Jackson said they received a call from a neighbor asking them to do a welfare check on Thursday because they had not seen vehicles move, a usually loud dog bark or lights turned on in a house near them for multiple days.

Police also had received a call from the employer of one of the individuals who said they hadn’t seen them in a few days.

When they arrived at the home, no one answered the door and officers began making an effort to contact family or friends of those that lived in the house, Jackson said.

Officers were able to remove a window and enter the home. Once inside the house, they found the four individuals and a large dog dead with gunshot wounds, Jackson said.

Jackson said the family had no prior interaction with the Mapleton Police Department.

The bodies of the family are currently at the Utah Office of the Medical Examiners, according to Jackson’s Facebook post.

“Once the examinations are complete we will be able to shed more light on what is believed to have transpired in the home,” Jackson said in the post. “We don’t anticipate that those examinations will be completed today.”

The Police Department, which has eight full-time officers, is receiving assistance from the Utah County Sheriff’s Office on the investigation, which went on through Thursday night and continued Friday morning, Jackson said.

”It is a big deal for our community and it’s going to rock our community,” he said. “It’s going to tear some people up because these people here care about each other, so this will hit them hard. But they will come together, they always do.”

Lana Hiskey, spokeswoman for the Nebo School District, said they will have grief counselors available at Maple Mountain for those who need assistance during this difficult time.
