A Pekin man went to jail this week, more than 2 1/2 years after he forced an hours-long standoff with heavily armed police at his home.

Frank Fink, 51, was sentenced to 90 days after he pleaded guilty Tuesday to misdemeanor possession of a firearm. The charge was reduced from possessing a firearm with a revoked FOID card, a felony.

For about five hours into the night of Jan. 31, 2015, Fink refused to emerge from his home at 323 S. Fourth St. as a Central Illinois Emergency Response Team waited outside. Surrounding streets were closed and neighbors were told not to leave their homes during the standoff.

It began at about 4 p.m., when neighbors reported Fink fired at least one shot from a handgun outside his home and returned inside.

When police requests for anyone inside to come out went unanswered, the CIERT team sent a remote-controlled, camera-mounted robot inside the home. It climbed a flight of stairs and made contact with Fink’s son, who was sleeping in his bedroom, police said.

Fink, however, remained in the home until about 9 p.m. before he emerged and was arrested without further incident. Police said alcohol did not play a role in the incident, but other reasons for Fink’s behavior remained unclear.

Initially cited for obstruction of justice as a city ordinance violation, he was charged with the firearms-related crime several months later after police confirmed he had been in possession of a loaded firearm.

Fink also must pay $657 in court-related costs, but restitution was not ordered for police overtime and other costs related to the standoff. He will be given day-for-day credit on his jail sentence.
