A Fort Worth police officer was driving at least twice the legal speed limit when he struck and killed a 27-year-old mother of two, police said Tuesday.
Jesus Cisneros, 37, was charged with intoxication manslaughter Monday in connection with the early-morning wreck that killed Sonia Baker. He turned himself in later that day and also submitted his resignation after the Fort Worth Police Department issued the arrest warrant.
Tests revealed Cisneros' blood alcohol content was .17 -- more than twice the legal limit -- when his unmarked car collided with Baker's on Dec. 11, investigators said.
The off-duty officer was driving westbound at about 2:30 a.m. in the 3800 block of Columbus Trail as Baker attempted to turn in front of his vehicle, police said. An affidavit released Tuesday said Cisneros was driving "at least twice the posted speed limit" at the time of the crash. The posted speed limit on Columbus Trail is 35 mph.
Baker, a 27-year-old wife and mother of two boys, ages 4 and 5, was on her way to pick up breakfast before heading to work, her family said.
Cisneros was released from the Tarrant County Jail after posting $25,000 bond -- the maximum for intoxication manslaughter.
He has been an officer with the Fort Worth Police Department since September 2001.
"This tragedy has shocked the conscience of this department. I will deal swiftly with Officer Cisneros," Chief of Police Jeffrey W. Halstead said after the blood tests results were announced. "The police department is deeply saddened for the Baker family. We are embarrassed by this tragic incident."
