Federal authorities say a man charged with killing a woman and raping her 10-year-old daughter after a carjacking at a New York mall last week was able to remove and reassemble his court-ordered electronic monitoring bracelet in about a minute before carrying out the attacks.
A U.S. probation officer says 29-year-old David Renz managed to cut the device from his ankle and put it back together so quickly that it didn't prompt the company in Colorado that makes the monitors to notify court officers in Syracuse.
The official says the officers had told the company not to notify them when the ankle monitor's signal was interrupted for a short period of time because the officers were getting tampering alerts every time the devices were knocked against bathtubs or walls.
New York State police say the events started unfolding at about 9 p.m. last Thursday at the Great Northern Mall in Clay.
Police say the 47-year-old woman was leaving a gymnastics class with her 10-year-old daughter when Renz stopped them.
Troopers say Renz raped the girl in the family's vehicle and then drove the victims a short distance to Verplank Road in the Town of Clay.
The girl managed to escape the vehicle and was assisted by a passing motorist.
The man then stabbed the woman multiple times. She was rushed to Upstate University Hospital in Syracuse where she died.
Renz, of Lakeshore Road in Cicero, is charged with murder, rape and kidnapping.
