Authorities are searching for their 22-year-old adopted son, Dylan John Bennett, who is one of the prime suspects in the couple's murder.
The Bennett's were found dead on Wednesday after a friend went by the house to check on them after calls and texts went unanswered.
According to a statement made by Todd County Sheriff’s office, the two of them died under "suspicious circumstances."
Even though the Bennett's son is still wanted as of Friday, the police have said there isn't a threat to public safety.
Bennett was selected by the Saints in the third round of the 1978 NFL Draft, spending his first four years with them before going to the Jets, where he spent the next six seasons. He then played two games in 1988, one with the Jets and one with the Minnesota Vikings.
In 132 career games, Bennett totaled 18.5 sacks, including his highest total of 7.5 in 1985 with the Jets.
