A Trumbull man was arrested for driving under the influence after crashing his car on the Merritt Parkway, threatening in the second degree, and interfering with the duties of an officer at 9:08 p.m. Saturday, Aug. 29.

Police said that Staff Sgt. Heber Meraz, 46, of Midland Road failed one field sobriety test and refused to take another after crashing his car into a guardrail on the southbound entrance ramp of the highway near Route 108, and proceeded to defecate himself as arresting officers put him in the back of a Trumbull police cruiser.

A report said that Meraz was transported to police headquarters where he was told to clean the excrement that was all over his legs and feet. Instead of complying to the officer’s request, police said, Meraz got combative and yelled at the cops before he began to eat his own feces in front of them.

Meraz told officers that he was a U.S. Marine who fought in Afghanistan, and threatened that he would have them fired because he knew First Selectman Tim Herbst, Bridgeport Mayor Bill Finch and mayoral contender Joseph Ganim.

He continued to be belligerent, the report said, targeting one Trumbull police officer specifically and threatening the officer’s family.

Meraz declined to give the cops his personal information and refused to be fingerprinted, while he kept trying to provoke the officer to fight him.

Police said he smeared some excrement on the wall of his jail cell.

He was held on a $2,500 bond for the DUI charge, as well as driving without insurance and failure to drive right. He was held on an additional $500 for threatening the officer.

He’s schedule to appear in court on Wednesday, Sept. 9.
