“We do not know, we were on the phone with the third person who was not there, and he disconnected the call,” the dispatcher later continued.

Wilson’s cousin Dakota Sweeney, 28, was arrested and charged with murdering their grandmother, Gayle R. Wilson.

Sweeney was arrested by the Carrollton Missouri Police Department on April 22 and charged the next day with first degree murder and armed criminal action, according toa statement from Missouri State Highway Patrol.

Gayle, 75, was West and Sweeney’s grandmother, according toher obituary.

The Missouri State Highway Patrol said that at 10:25 p.m. last Wednesday, Carroll County law enforcement officials reported to a shooting at a residence and found a female deceased inside.

A witness on the scene allegedly identified a male suspect who was taken into custody without incident, the statement said.

Sweeney is currently being held at Caldwell County Jail on a no-bond warrant.

Missouri State Highway Patrol’s Division of Drug and Crime Control is currently investigating the homicide.

Wilson, 31, has been in the headlines due to his shocking romance with his “Summer House” co-star Amanda Batula, after he had previously dated her BFF, Ciara Miller.

Despite the backlash, Wilson and Batula, 34, are going strong.
