Four people have been arrested in connection with the deaths of a rural eastern Missouri couple following a fire at their home.

There have been no formal charges filed at this time for the suspects who are all from Iron County. The suspects range in age from 18 to 24. Authorities have not disclosed a possible motive.

The fire broke out before dawn Monday in a rural area near Park Hills in St. Francois County, killing 50-year-old Stanley Halter and his 46-year-old wife, Tammy. Both of the victims’ bodies were found inside their home. Their children had spent the night with a relative.

St. Francois County Sheriff Dan Bullock declined to give any further details about the arrests.
