BELFAST — Sherry Johnson, mother of Jessica Trefethen, who was charged last June with the murder of her 3-year-old son, pleaded not guilty of concealing her daughter’s whereabouts. Johnson was arraigned Jan. 11 at Waldo County Judicial Center.

The 59-year-old Stockton Springs woman was charged with hindering apprehension or prosecution, a Class B offense, after police confronted her with video surveillance showing she did not drop her daughter at the Searsport public boat launch June 20, 2021, as she had previously said she had. 

Johnson later admitted not dropping Trefethen  off at the pier, but instead driving to Bucksport with her daughter and returning to her home later that day. Court documents also show Johnson denied knowing her daughter’s whereabouts a few days later on June 23, but when detectives arrived at her home, she admitted Trefethen was inside.

Johnson and Trefethen took Maddox Williams, Trefethen’s son, to Waldo County General Hospital June 20 after the boy became unresponsive, according to a police affidavit. Court documents show Trefethen told hospital staff the boy had been knocked down by a dog leash and kicked by his 8-year-old sister.

The hospital reported he was not breathing and had no pulse when he arrived and that staff were unable to resuscitate him. Maddox was pronounced dead at the hospital. Maine State Police arrested Trefethen June 23, after the state medical examiner ruled the death a homicide caused by multiple blunt force trauma.

Superior Court Justice Robert Murray scheduled an Oct. 24 court date, saying current bail conditions will continue. Johnson’s bail was set at $2,000 cash or $20,000 worth of real estate with conditions she not have contact with several people, including her daughter. Class B crimes carry sentences of up to 10 years in prison and/or a fine of up to $10,000.
