Steven Armbruster died of complications from a brief illness, Lehigh County Sheriff Joe Hanna told WFMZ.
Hanna did not immediately return Daily Voice's call Wednesday morning requesting the cause of death.
He worked as a deputy sheriff since 2013, and prior to that, he served in the United States Army and military police, according to a post from the sheriff's office.
The sheriff's office remembered him as a consummate professional.
He leaves behind his wife, Tara, a daughter Madison, and two sons, Steven and Samuel.
Funeral services will be held at a later date.
