A Pennsylvania man has been charged with attempted murder after his mother was rushed to a hospital on Thanksgiving, authorities said Monday.

Michael Giffing, 42, was arrested after EMS responded to a call of a person who was unconscious from a fall at a home in the 300 Block of W. Ashbridge Street in West Chester on Thursday evening, the West Chester Police Department said.

As first responders raced to the home, the call was upgraded to a possible cardiac arrest. 

Giffing’s mother, Dorothy, was rushed to a hospital. However, police said her injuries "were not consistent with a fall."
