Katherine Ann Demianczyk, known as Katie, was 25 when she vanished from the Philadelphia area around 2018. Born January 31, 1993, she spent her early years in Coral Springs, Florida, and moved to Pennsylvania about age twelve. By her mid-20s Katie was a mother and experiencing homelessness, frequently in Kensington in Philadelphia and sometimes in Toms River and Farmingdale, New Jersey.

Katie was petite, between 5 feet 0 inches and 5 feet 2 inches, with blue eyes, often dyed bright hair (purple or electric blue) and distinctive piercings under her left eye, on her upper lip and her nose. The last time her mother saw her in person was with her boyfriend two days before Thanksgiving 2017; the last verbal contact was a phone call in early August 2018. Her final known social media activity was an Instagram post tagged at an IHOP on Aramingo Avenue on August 11, 2018, after which her phone and online presence went silent. Family searches in October 2018 and other efforts have not produced answers.

Katie left behind a young daughter and a family that continues to seek information. If anyone knew Katie’s movements in Philadelphia or the Jersey Shore in mid to late 2018, please share what was seen or heard.
