Oklahoma woman charged with killing 4 people with car to appear in court

STILLWATER, OKLA. (Reuters) -- A woman suspected of plowing her car into a crowd at a homecoming rally for Oklahoma State University, killing four and injuring dozens, is set to make her first court appearance on Monday to answer to four counts of second-degree murder.

Adacia Chambers, 25, is suspected of driving while intoxicated when she rammed her gray Hyundai Elantra into a crowd watching Saturday's parade in Stillwater, killing three adults and a toddler, police said.

Chambers was expected to make an initial appearance in Payne County District Court on Monday afternoon, police said.

Four dozen people were also injured, five of them critically, in the accident that sent shockwaves through the college town about 70 miles west of Tulsa. The crash was captured on mobile-phone video and seen globally.

Second-degree murder charges can bring between 10 years and life in prison. Police were awaiting results of a blood test administered to Chambers after the crash.

Her lawyer, Tony Coleman, told cable news channel CNN that when he told his client of the deaths and injuries, there was "no show of emotion whatsoever - zero response. That is not something that is typical of a normal, functioning individual."

Coleman told reporters on Sunday he believes his client is mentally ill and doubted she was drunk at the time of the crash.

"In my opinion, Ms. Chambers suffers from a mental illness," Coleman was quoted as saying by the Tulsa World newspaper. "Exactly what type is yet to be determined."

A man who was watching the parade with his family said the crash sounded like a bomb had gone off, transforming the festive school rally into a blood-soaked crime scene.

Killed on the scene were Bonnie Stone and Marvin Stone, both 65 and of Stillwater, as well as Nikita Nakal, 23, of Mumbai, India. Two-year-old Nash Lucas, of Weatherford, Oklahoma, died later at a hospital, police said.
