A prominent central New York physician has been sentenced to 20 years to life in prison for killing his estranged wife inside their mansion and trying to cover up the crime.

Sixty-three-year-old Dr. Robert Neulander was sentenced Thursday in Onondaga County Court. The judge says he didn't impose the maximum sentence of 25 years to life because of pleas for leniency by the victim's family.

Neulander had been found guilty of second-degree murder and tampering with physical evidence.

Onondaga County prosecutors say the obstetrician-gynecologist killed 61-year-old Leslie Neulander in a fit of rage inside their home in suburban Syracuse in September 2012.

Robert Neulander told investigators his wife had slipped in the shower and he had carried her into the bedroom. The Neulanders were getting divorced at the time.
