Springville • Police on Saturday night said a couple and their three children were found dead in a home here.

The names of the deceased were not immediately released. The home, a duplex, is near 900 S. 1000 East in Springville.

The residents on the other half of the duplex were unharmed.

Springville police Lt. David Caron said a medical examiner will determine what killed the family.

"Right now there's no known cause of death," Caron said at a 9:45 p.m. press conference in front of the duplex. "There's nothing obvious."

Caron said firefighters tested the air and did not find any carbon monoxide, but the gas could have ventilated before the test.

"This time of year, it's obviously something we're concerned with," Caron said of the possibility of carbon monoxide.

The parents were ages 36 and 37, Caron said. Two boys were ages 14 and 11 and a girl was 12.

Another relative spoke to family on Saturday morning, Caron said. When that relative went to the house shortly before 8 p.m., the family was dead. That relative called police.

Springville is on the southern half of Utah County. The county's bedroom communities have been the scenes of unusual deaths and grisly discoveries this year.

On Jan. 16, Lindon police officer Joshua Boren murdered his wife, his mother-in-law, his two children and then himself. A police investigation revealed Boren and his wife, Kelly Boren, had a volatile marriage.

Pleasant Grove police in April discovered Megan Huntsman had killed six infants between 1996 and the end of 2006. Huntsman has been charged in Provo's 4th District Court with six counts of first-degree felony murder.
