Brenda (Slagle) McCartney, 58, of Bruin, PA passed away on March 30, 2024 at her parent’s home in Butler. Brenda was tough as nails but sweet as candy. She is finally resting after a frustrating 2-year battle with cancer. She loved her family, nature, crafting and crocheting. Years ago, she was an active girl scout leader with her daughter in Troop 462. From spending so many years working in automotive parts and repair, she really knew a lot about vehicles. She was the manager of her own repair shop in Slippery Rock, PA. She was born in Grove City, PA on January 3, 1966. She is survived by her daughter Lierynne McCartney; her parents Dean and Peg Slagle; brothers Gary (Marie) Slagle, Bill Slagle, Schon (Amy) Slagle; her grandchildren Lily, Jaxon, Ravyn, and Zane; her nephews Jacob (Kayla), Gabriel (Kaitlyn), Will and her niece Ashli (Chandler); aunt Dori (John), aunt Linda, uncle Bill and a great number of cousins. She was preceded in death by her grandparents Vi and Bill Slagle, Albert and Betty Youkers, along with some uncles and an aunt. According to her wishes, all services were held privately through the SPENCER D. GEIBEL FUNERAL HOME & CREMATION SERVICES, 140 NEW CASTLE RD. BUTLER, PA 16001. WWW.SPENCERDGEIBEL.COM. A celebration of life will be held at a later date. In lieu of flowers, donations may be made to the UPMC Hillman Cancer at Butler Health System at 129 Oneida Valley Rd. Ste 311, Butler, PA 16001.
