Ex-NASA astronaut who killed two sisters, aged 11 and 13, in fatal crash when he rear-ended the car they were in after he spent hours drinking in a motel room is sentenced to four years in prison
Former NASA space shuttle commander James Halsell Jr. caused a horrific car accident in his native Alabama that killed two young sisters back in 2016
Halsell was initially indicted on reckless murder charges at the time of the crash after refusing a blood-alcohol test
The former astronaut ultimately pleaded guilty to reduced charges on Thursday
While Halsell was originally facing a decades-long prison sentence, an Alabama judge agreed to just a four-year sentence with 10 years probation
