Vital Statistics
Circumstances of Disappearance:
She spent some time at a bar on Main Street in Newmarket before moving on to a local night club with three acquaintances, including 27-year-old Pol Classen. Lamondin and Classen then attended a party at a house on Millard Street in Stouffville which belonged to Classen's sister. After the party, Classen drove her to Fairy Lake Park in Newmarket, a popular meeting place for local youth. According to Classen, he dropped Lamondin off at Fairy Lake around 02:00 on the morning of Saturday, 29 May 1999; this was the last time anyone saw her alive. When she was last sighted, Lamondin was wearing blue denim overalls with blue-and-red-striped straps, a yellow tank top, and Birkenstock sandals with three straps and flowers painted on the side. She often wore silver jewelry, and may have been wearing a black string medallion necklace.
Additional Details:
York Regional Police carried out the initial stages of the search for Tammy Lamondin. Police divers searched Fairy Lake but recovered no remains or evidence connected to the case. In July, police confirmed a behavioural psychologist was assisting in the investigation. In the early days of the investigation, police questioned Classen twice but avoided calling him a suspect, although they told the media no one else was being investigated. The investigation focused on what Classen had done between when he allegedly dropped Lamondin off at Fairy Lake Park at 02:00 and when he used his bank card in Stouffville at 06:43, nearly five hours later that morning. He hung himself June 7th. Police are reluctant to call Classen a suspect, but they will say that no one else is. Certainly his death and the manner of his death has elevated our concern in regards to the relationship to Tammy Lynn's disappearance and we're investigating. The night after Lamondin disappeared, Classen rented a carpet cleaner from a local A&P supermarket. According to police, Classen also returned to the bar where he and Lamondin had been on the night of her disappearance and told the manager he had spotted her alive on Main Street since the disappearance. A memorial service was held for Lamondin on 8 October 2003, more than four years after her disappearance, and her family filed to have a death certificate issued in her name in 2015 after 16 years without any communication. As of 2021, Lamondin's disappearance is being treated as a cold case and investigated by a homicide unit within the York Regional Police. In 2016, three journalism students at Carleton University produced a 5-minute documentary about Lamondin's case, Tammy's Story, which was broadcast four times by TVO on 5 and 7 November 2016 before later being uploaded online. Lamondin's case is one of three featured as part of a recurring memorial exhibit, 'Shades of Our Sisters', which tells the stories of missing and murdered Indigenous women, transgender, and two-spirit people from the perspective of their families.
