Faulkner County Sheriff Andy Shock confirmed Monday afternoon the death of Faulkner County Sheriff's Office deputy Hans Fifer, 32, of Mayflower.
According to Shock, Fifer was with a group of five deputies Monday morning participating in SWAT team tryouts at DARC training facility in North Little Rock.
Following a course including running, jumping and shooting exercises, Shock said Fifer began complaining of chest pains.
Medical personnel at the scene performed CPR before transporting Fifer to Springhill Baptist Medical Center for treatment, where he was later pronounced dead.
Shock said initial reports indicate Fifer died due to heart complications.
The FCSO family is taking the loss "very hard," Shock said.
"It’s close to home," he said. "We are a huge family."
Shock called the loss "totally unexpected" and said Fifer was in "very good shape."
Fifer joined FCSO in January at the beginning of Shock's term as sheriff.
He had previously worked as a reserve deputy with the department, before working as a patrolman with Cabot Police Department, where he received his training and certification.
Fifer leaves behind a wife and two young daughters, ages 3 and 5.
Shock said his decision to hire Fifer in January "happened in an instant."
"Hans was a perfect example of what a policeman should be," Shock said. "He was very kind-hearted. He had a servant's heart. He was very humble."
Shock has asked for the prayers of the public for Fifer's family and the department.
"It's just a really rough time and we hope that God will surround his family with peace and comfort," he said.
Funeral arrangements have not yet been made.
