Roger Nielson, 65, a Lodi, California resident, was found dead in his home on May 27, 2021 during a wellness check requested by a concerned family member. Deputies determined he had been shot and the death was treated as a homicide.

Investigators identified his son, Richard Nielson, then 32, as the primary suspect. Richard had left for Mexico on May 23, 2021, in violation of probation. U.S. Marshals, working with Mexican authorities, located and arrested him in Guadalajara in early June 2021; he was deported and taken into custody by the San Joaquin County Sheriff’s Office.

Richard Nielson was charged with first-degree murder and intentional discharge of a firearm causing death. The case involved local, state and federal agencies in the investigation and extradition. If anyone knew Roger or saw him around May 2021, what information can be shared with investigators?
