 A York County jury took just an hour yesterday to convict Randall J. Hennessey of murdering his landlord, Douglas Michaud Jr., in Biddeford in 2021. Michaud was trying to evict Hennessey when he was killed. Almost 750 million gallons of heavy untreated sewage and stormwater flowed into Maine's waterways last year, more than double the amount in 2022.
