A quiet Sunday afternoon in Warren, New Jersey, turned tragic in August 2015, shattering the peace of the affluent community. Heidi Errickson, a 45-year-old female, became the victim of a shocking act of violence that would leave a lasting scar on her family and the town she had always called home. A lifelong resident of Warren, Heidi was known for her nurturing nature, which she expressed both in her personal life and in her work as a paraprofessional at Central School. Her greatest joy and achievement, she would often say, was being a mother to her son.
On that fateful day, an argument between Heidi and her fiancé, John Reno, escalated to an unimaginable horror. In their Warren Township home, Reno, aged 48, fatally shot Heidi. The violence did not end there. Shortly after, Heidi’s brother, 55-year-old Frederick Errickson Jr., arrived at the residence, apparently to check on his sister’s welfare.
He was tragically met with the same fate, shot and killed by Reno in the driveway.
What followed was a tense standoff with law enforcement that lasted for approximately six hours, with nearby homes evacuated as a precaution. The search for the suspect concluded when authorities discovered John Reno in a wooded area behind the home. He was found in a drainage ditch with a self-inflicted gunshot wound to the head. Beside him lay an assault rifle and two high-capacity magazines. The investigation concluded that Reno was the sole perpetrator in the deaths of Heidi Errickson and her brother, ending the ordeal in a grim murder-suicide and leaving a community to mourn the senseless loss of two of its own.
