FOX 7 has obtained video of a man's DWI arrest prior to his involvement in a crash earlier this year that killed two siblings from Liberty Hill.
In Round Rock police dash camera video from August 1, 2009, an officer pulls over a Jeep driven by John Canche Alvarado. The officer says Alvarado failed to use his turn signal.
The officer asks him how much he's had to drink.
Officer: "So, you said you had three beers tonight?"
Officer: "Okay. Were they bottles of beer? Cans of beer?"
An hour into the traffic stop, Alvarado starts talking about going to jail.
Alvarado: "Um, officer, um I understand that we are gonna go to jail tonight?"
Officer: "Why do you think you're going to go to jail?"
Alvarado: "I know we're going."
The officer then asks to run him through field sobriety tests to make sure he is able to safely drive away. He refuses.
Officer: "No, you don't want to do the tests?"
Alvarado: "Yeah, cause that gets you into trouble."
Officer: "Well, if you're not intoxicated. Do you feel that you're intoxicated?
Alvarado: "No, but if I make a mistake then I'm in trouble and I'm on camera."
Alvarado did not have a driver's license. When the officer asked about it, Alvarado said he would not answer any more questions.
Alvarado: "You're going to take me to jail, right?
Alvarado: "Okay, well."
Alvarado turns around to allow the officers to put handcuffs on him. He is taken to the Williamson County Jail. The arrest would lead to his second DWI conviction.
Alvarado's first DWI arrest was in 2008. A woman told police he was driving erratically on Lakeline Boulevard in Cedar Park and struck a curb causing two tires to blow out. He was convicted and sentenced to 20 days in jail.
On April 22nd of this year, Alvarado was arrested again for another alcohol-related offense. He was charged with two counts of intoxication manslaughter.
Alvarado's girlfriend told state troopers he had been drinking and he was on his to her house when he rear-ended a Nissan Altima driven by Crystal Draper. Two of her four children inside the vehicle were killed--nine-year-old Kirsten and 15-year-old Koby. Crystal and her other children were seriously hurt.
If convicted, Alvarado could face up to 40 years in prison. The case could potentially qualify for the charge of felony murder. If prosecutors change the charge, Alvarado could face up to life in prison.
