PORT RICHEY, Fla. (AP) — Authorities say a Florida man who made death threats against Iowa’s governor and other state officials has been arrested. The Tampa Bay Times Pasco County deputies arrested 59-year-old Richard Gillow on Monday and charged him with making written threats to kill.

Authorities say the Port Richey man posted on Facebook and sent emails saying he was going to kill Iowa Gov. Terry Branstad, Lt. Gov. Kim Reynolds, Attorney General Tom Miller, Guardian Ad Litem Kim Ayotte and an employee of the state’s Department of Human Services.

An investigator in Iowa tipped off Florida authorities to the threat. Officials say Gillow believed the Iowa officials were involved in the removal of his grandchildren from his daughter’s custody. Gillow was freed on $10,000 bail.
