Casa Grande, Arizona: The Pinal County Sheriff's Office announced the arrest of 21-year-old Richard Wilson Jr. after officers responded to a frantic 911 call from a residence around 1:45 pm on Sunday, September 4, 2022.
"This act of depraved violence will have long lasting effects on all those who knew this family," Sheriff Mark Lamb said in the release. "While nothing will bring their loved ones back, I send my prayer and support to everyone effected."
Wilson has been charged with four counts of first degree murder and is being held on a $2.5 million bond.
The Associated Press reports that the Sheriff's department disclosed that they had been called to the residence 10 times over the last three years.
On Sunday, it was Wilson's 16-year-old sister, Rudy Wilson that called 911. Ultimately that call was disconnected.
When officers arrived, they contacted Wilson as he exited a fifth-wheel trailer on the property with injuries to his right hand and blood on his clothing. Wilson reportedly told the officers, "I'm over here. Take me to jail."
When asked if there was anyone inside the home, Wilson reportedly told them to go look.
According to Chief Deputy Matthew Thomas, what officers found inside was "quite a horrific scene. Our guys and gals that showed up there were deeply affected by this."
Officers located the bodies of his father, 47-year-old Richard Wilson Sr., his mother, 50-year-old Ellen Otterman, his sister Rudy, and his 5-year-old niece, Renaya White.
All appeared to have been stabbed.
One neighbor, Wanda Hamilton spoke with Inside Edition saying and expressed her shock saying, "Not him. I talked to that kid all the time."
The investigation is ongoing and Wilson's next court date is not known at this time.
