Fort Dodge Police investigate the death of the Rev. Al Henderson Wednesday evening at St. Paul Lutheran Church.

He is charged with first-degree murder, a class A felony; and first-degree robbery, a class B felony.

Pendleton has had previous criminal mischief, disorderly conduct, interference with official acts and assault charges, according to court records.

Henderson’s impact was felt throughout the Fort Dodge community.

He was profiled by The Messenger in September for his work with Serving Our Servants, a group formed to support and appreciate public servants. The group was formed about five years ago.

SOS helps with things like providing water and food at major incidents to raising money to buy the Fort Dodge police officers new dress caps that they can wear for formal occasions.

Henderson was the chaplain for the Fort Dodge Police Department, Webster County Sheriff’s Department, Iowa State Patrol and Fort Dodge Fire Department.

He became the pastor at St. Paul Lutheran Church during a time of adversity.

Five months prior to his hiring, an early morning fire destroyed the 113-year-old church the St. Paul congregation was housed in.

“I really see my primary role as supporting the congregation through the mourning and rebuilding process,” Henderson said at the time.

He added, “Leadership and guidance would be second because leadership is already here. They have moved on and are already preparing, seeking and dreaming.”
