South Carolina police have arrested a man who allegedly conspired with Alex Murdaugh, a high-profile attorney whose wife and son were murdered in a double shooting in June, to shoot and kill him in a plot to garner millions in life insurance payouts to his son.

"Agents of the South Carolina Law Enforcement Division Tuesday arrested a Colleton County man in connection with the shooting incident involving Alex Murdaugh on Sept.

4 in Hampton County," South Carolina Law Enforcement Division spokesman Tommy Crosby said in a statement.

Curtis Edward Smith, 61, faces charges of assisted suicide, assault and battery, pointing and presenting a firearm, insurance fraud and conspiracy to commit insurance fraud in connection with the case, according to the South Carolina Law Enforcement Division.

Investigators said they have probable cause to believe Murdaugh set up the plot himself – but survived the shooting attempt with a superficial wound to the head, according to a SLED affidavit.

Additional charges are expected in connection to the Murdaugh case after state investigators joined the case at the request of the Hampton County Sheriff's Office, Crosby said.
