Davier Massey, 28, is accused of storming the Planet Fitness workout facility twice on Thursday. Police said Massey was outraged after being banned the day before because of an unpaid bill. He arrived at the gym sometime in the morning but quickly left.
At 12:30 pm, Cheltenham Township Police Department was dispatched to the business over claims that Massey stormed the building and caused a violent disturbance. Arguments between Massey and the gym employee escalated, prompting the suspect to allegedly stab the victim multiple times. A male patient with multiple stab wounds was located and transported to an area trauma center for treatment for life-threatening injuries.
The victim has not been named but is reportedly recovering at the hospital. Cheltenham's Planet Fitness was closed the rest of the day following the incident. Police arrested Massey a short distance away within the Cedarbrook Shopping Plaza.
He was charged with attempted first-degree murder, aggravated assault, reckless endangerment, harassment, making terroristic threats, criminal mischief, disorderly conduct, simple assault, and possession of an instrument of crime. According to his LinkedIn page, Massey worked as a case manager at Morgan & Morgan until mid-2024 and earned a Bachelor's degree in Criminal Justice.
