Pablo Santiago, a well-known Mercer County sheriff's officer, was found dead inside the Mercer County Administration building on South Broad Street in Trenton Wednesday afternoon of an apparent self-inflicted gunshot wound, authorities said.

Santiago, who held the rank of detective, was found at about 1:15 p.m., reports

Mercer County Sheriff Jack Kemler announced his death late Wednesday:

"This tragedy is a very sad reminder of the pressures that law-enforcement officers experience on a daily basis," Kemler said. "Our hearts break when a law enforcement officer in our community dies under any circumstances. I know that all of our Sheriff's Officers feel a terrible loss today. Our thoughts and prayers are with Det. Santiago, his family, his friends and colleagues."
