A month after the suicide of Tom Schweich, Republican candidate for the governorship of Missouri, his spokesperson, Robert "Spence" Jackson, has also committed suicide. Police are investigating his death.

On Sunday, the Jefferson City police discovered the body of Jackson, 44, at his home, according to KMOV. He apparently died of a self-inflicted gunshot wound. Police suspect he shot himself late on Friday or early on Saturday, police spokesperson Capt. Doug Shoemaker said.

Police arrived at his apartment after his mother called them, not having heard from Jackson for some time. With a key to the apartment provided by the property manager, the police entered and found his body in the bedroom.

There was no sign of struggle or forced entry, according to Capt. Shoemaker, and they found a note as well as the weapon. The police have yet to release the contents of the note.

The death of Jackson comes a month after his boss, Missouri Auditor and GOP gubernatorial candidate Tom Schweich, shot himself in his Clayton home. Schweich had arranged for interviews with reporters minutes before he took his life. The politician accused a party member of anti-Semitism.

Jackson stood by his late boss's stance and had called on John Hancock, recently appointed chair of the Missouri GOP, to resign over the allegations of anti-Semitism levied against him by Schweich.

According to the St. Louis Post Dispatch, police found a .357 Magnum revolver and a spent cartridge, along with the note. Capt. Shoemaker added that the police does not believe Jackson's suicide is related to Schweich's, but they have contacted the Clayton Police Department.

After the news broke of Jackson's death, many state politicians expressed their condolences. Jackson worked for Schweich for four years and before had served as communication director for former governor, Matt Blunt.

"Spence was hard-working, well-liked and quick-witted. He will truly be missed. We mourn his passing and offer our prayers to his family and friends," the former governor said, calling Jackson "a good friend for many years."
