A man has been accused of chopping off his mother's head with a hacksaw, then doing a runner and leading police on a chase.
Officers were called to the Texas home of Isaac Israel Warriner, 22, and Sarah Warriner, 65, on May 5 after a neighbour reported him "acting weird".
The caller stated that Warriner had all types of cleaning supplies with him and was possibly making a bomb, an affidavit states.
When officers arrived, he had vanished but they found a shopping cart containing various cleaning supplies outside.
The door to the pair's apartment was unlocked and when police went inside they found Mrs Warriner's headless body in a state of decomposition.
They believe she had been dead for two days.

Evidence in the bedroom led them to believe a hacksaw was used to severe her head, which has not yet been found.
Isaac Israel Warriner was arrested in neighbouring Oklahoma when he was spotted in his mother's car the following day and led police on a chase before he was caught.
He was returned to Denton and booked in the jail on Thursday evening.
He is facing several charges, including abuse of corpse and tampering with physical evidence.
He has not been charged with killing his mother.

Days before her death, Mrs Warriner had taken her son to hospital after he used a razor to cut his arms, an affidavit said.
A nurse called security when he threatened to kill his mother and himself.
Police were called, but he fled the hospital before they arrived.
A ruling on the death of Mrs Warriner is still pending, according to officials with the Tarrant County medical examiners’ office.
Isaac Warriner's father Kenneth Warriner told the Fort Worth Star-Telegram earlier this month that his son had had a mental breakdown just months before the body of his ex-wife was found on May 5.

Mr Warriner told the paper in a May 6 interview: “She had allowed Isaac to stay with her after his last rehabilitation stay.
“He was prescribed psychotic drugs to try and help, but that didn’t seem to work.”
The dad later took to Facebook and said: "As Isaac's father and the person that would be most affected by this crime I would have to say that hate only propagates hate so therefore try and forgive and understand that we're dealing with mental illness and demonic possession on a scale unprecedented by anyone that could possibly understand."
