Police say Colo. man accused of dismembering mother told them he recently learned he wasn't in her will

(CBS/AP) CENTENNIAL, Colo.- The man who was arrested Wednesday after police found the dismembered remains of his mother in the back seat of his car says he recently learned that he was not in his mother's will, according to the Associated Press.

Ari Liggett, 24, is being held without bond on suspicion of the first degree murder of Beverly Liggett, 56. He was arrested near his home after crashing his car in an attempt to elude police, CBS Denver reports.

Liggett originally told the interviewing officers he had found his mother dead in the living room after she committed suicide.

A search in the family's home uncovered a saw in the dishwasher and potassium cyanide and traces of blood in the freezer and bathrub, according to court records.

"There's no words to describe what could really bring somebody to do that," said neighbor Brett Wilbur. "I don't understand how that's possible in the first place. There's got to be some sort of mental illness, I pray God just has mercy on his soul."

CBS Denver contacted Ari Liggett's father who said that his son "absolutely" had mental health issues. Liggett, who was on probation for carrying a silencer at the time he was arrested, apparently had had interactions with the Sheriff's department for years.

Investigators continue to search Liggett's home to collect and analyze evidence. Charges are expected Tuesday.
