A man has been arrested for allegedly killing his own mother and then trying to blow up her Illinois home in an attempt to hide the evidence. On December 27, police discovered the body of 72-year-old Terrie "Tracy" Nguyen while conducting a wellness check after other family members had been unable to reach her for some time. O'Fallon police Lt. Patrick Feldhake said that the cause was still "undetermined" as of Wednesday, December 31, but Tracy's death was determined to be suspicious and violent. Her son, David Nguyen, 38, was swiftly identified as a "person of interest" in the case, according to a press release published by the O'Fallon Police Department. "At approximately 4:30pm that same day, the Missouri State Highway Patrol located David traveling westbound on Interstate 70 near Concordia, Missouri," the press release read. "David attempted to flee from troopers but was taken into custody following a crash on I-70 at mile marker 51. David was transported to a local hospital for treatment, charged with felony fleeing, and subsequently released into the custody of the Lafayette County Sheriff's Department." Murdered Indiana Mom Filed for Protective Order on Christmas Before Death Prosecutors have since said that Terrie - who went by Tracy - died after someone placed "plastic wrap over her nose and mouth," per reports by the Belleville News-Democrat. Authorities further alleged that David, "with knowledge that Terrie Nguyen had died by homicidal means, concealed the death of Terrie Nguyen by activating unlit gas burners on a stove to fill the house with gas and left a lit candle inside the house with the intent to cause an explosion." Alongside his previous charges, on New Year's Eve David was additionally charged with one count of murder with intent to kill or injure and one count of concealment of homicidal death, according to Law and Crime. He is currently behind bars at the Lafayette County Sheriff's Department in Missouri and is expected to be moved to a facility in St. Clair County, Illinois, in the near future. Man Accused of Killing Mother of His Children, Leaving Her Body in Trash Can Prior to her death, Tracy worked as a nail technician in Collinsville, Illinois. Members of the town and visitors to her nail salon offered their condolences, thoughts and prayers in a local Facebook group as they remembered her as happy, friendly and kindhearted. "So heartbreaking! [Tracy] didn't deserve this nor the Nguyen family," one Facebook user wrote. "[Tracy] was the sweetest person and treated everyone like family. She will so be missed." A second person penned, "My heart is absolutely shattered!!! Tracy was such an angel and treated me like we were lifelong besties every time I went!" and a third person commented, "I hope her family and friends take to heart how many people Tracy touched each day. Always a smile and a hello that was so cheerful." Another "heartbroken" former patron called Tracy "the sweetest lady" who "always had a smile for everyone." "I've been going there for 20 years and just can't believe it," the Facebook user added. A memorial service for Tracy will be held at a later date.
