(CNN) -- Arthur Sedille was up-front with police: He would often put a gun to his wife's head during fantasy sex play at their Oklahoma City, Oklahoma, home.

But Sedille said he didn't know the gun was loaded when he pressed it to his wife's head and pulled the handgun's slide back during sex on the night of December 21.

Now Sedille, 23, is facing the possibility of a murder charge in Canadian County, Oklahoma, in the death of his wife, 50-year-old Rebecca Sedille -- who died when the handgun went off in their bedroom.

According to a probable cause affidavit filed by Oklahoma City police, Sedille said the shooting was accidental. He called 911 afterward, according to police.

Investigators decided to arrest and jail Sedille on suspicion of first-degree murder out of an abundance of caution, said Oklahoma City police Master Sgt. Gary Knight. However, as of Tuesday afternoon, formal charges had not been filed in the investigation, which is ongoing, Knight said.

He declined to comment on investigators' findings so far.

Although a Canadian County judge found that probable cause exists to hold Sedille on the murder charge, assistant district attorney Paul Hesse said Tuesday he has yet to receive a report from police on the case. As a result, formal charges have not yet been filed, Hesse said.

Sedille remained jailed Tuesday in Oklahoma County, Oklahoma. Police in Oklahoma City -- which spans five counties and 700 square miles -- book all of their prisoners into that county's jail, Knight said.
