A man has been charged with stabbing his father to death with a sword at his parents' suburban Philadelphia home.



Twenty-six-year-old Eli Goodrich was arraigned Wednesday in Bucks County on criminal homicide and weapon possession charges.



Authorities allege in court documents that Goodrich, who recently moved to Philadelphia, was on a weekly visit to the family's Middletown Township home Tuesday when he said his father wasn't ``going to control my mind anymore'' and he had to kill him.



Investigators said the 67-year-old Alan Goodrich was found in a chair with a sword protruding from his stomach and was pronounced dead less than an hour later at a hospital.



A message couldn't be left Wednesday at a number listed for Eli Goodrich; court documents don't list an attorney who could respond to the charges.
