Seven-time Cup Series champion Jimmie Johnson has finally broken his silence more than a month after his in-laws and nephew were tragically killed in a suspected murder-suicide in Oklahoma. 

Johnson, who was recently named as a nominee for the NASCAR Hall of Fame Class of 2024, said he was "devastated" over the June 26 killings in a brief statement posted to Instagram on Friday.

They, along with her 11-year-old nephew, were found dead inside a Muskogee home on June 26 after law enforcement received a 911 call over reports of a disturbance and someone with a gun.

The Muskogee Police Department said in a statement at the time that officers responded to the scene and saw a person "laying in the hallway inside the front door." Shortly after, they heard a gunshot inside the home.

Police body cam footage released earlier this month revealed the horrifying scene where officers described seeing a victim through a window who was seen covered with a "blanket." Just before law enforcement entered an unlocked front door, the single gunshot could be heard.

The final victim was found in a bedroom.

Police told Fox News Digital at the time that they were investigating the fatal shooting as a possible murder-suicide and that Terry Janway was being looked at as a possible suspect.
