A former Connecticut police officer accused of mistreating prisoner Richard “Randy” Cox after he was paralyzed in the back of a police van pleaded guilty to a misdemeanor Wednesday and received no jail time, while three other officers chose to take their cases to trial. Betsy Segui, a former New Haven sergeant who supervised the city police station lockup, pleaded guilty to second-degree reckless endangerment in exchange for a 60-day suspended jail term. Another former officer, Ronald Pressley, took the same plea deal and received an identical sentence last week.
