Spence Jackson, the former spokesman for Tom Schweich, Missouri’s state auditor who shot and killed himself at his home in Clayton, Mo., last month, apparently took his own life Sunday evening at his home in Jefferson City, multiple Republicans with ties to Mr. Schweich said on Sunday evening.

Mr. Jackson, who had been working in the Auditor’s office following the suicide of  Mr. Schweich, was a close confidant of the Republican gubernatorial candidate. Jefferson City police on Sunday evening refused to weigh in on Mr. Jackson, saying they would have a comment on Monday morning.

Mr. Schweich killed himself amidst a contentious campign for governor, during which he believed he was the subject of an anti-Semetic whisper campaign and a brutal radio commercial.

Prior to joining Mr. Schweich’s office, Mr. Jackson had served as spokesman for Missouri Gov. Matt Blunt.
