HOUSTON - A man accused driving drunk and killing a homeless man and a 6-year-old in April is in trouble again.

Blaine Boudreaux, 35, is now accused of trying to obtain controlled substances.

After an investigation into where he allegedly received the drugs, prosecutors are charging him with Fraudulent Acquisition of a Controlled Substance.

State records show in the 15 months leading up to the wreck, Boudreaux got more than 64 prescriptions for painkillers and other drugs through 17 different pharmacies in Houston and Tulsa, according to police.

"It's commonly referred to as 'doctor shopping' or 'pill shopping'," said Alison Baimbridge, Chief of the Vehicular Crimes Section of the Harris County District Attorney's Office.

Prosecutors said Boudreaux even got three Hydrocodone prescriptions in one week by hiding information from doctors.

"If he's filling multiple prescriptions with multiple practitioners without letting them know that he's already filled those prescriptions and medications and different schedules, that's a crime," said Baimbridge.

"I'm not saying they're wrong," said Billy Skinner, Boudreaux's attorney, responding to the new charges. "I'm saying that they're two separate investigations."

Skinner says he's upset his client's arrest over the weekend and new $20,000 bond come just days after Boudreaux bonded out from jail on his previous charges.

"I'm sure the prosecution would love for Mr. Boudreaux to sit in jail because it makes it easier to eke out a plea," said Skinner.

Skinner later added, "What they're doing is stacking charges on top of another. I mean, the man's charged with four felonies."

Houston police said he was high on those prescription drugs when he was involved in the two fatal accidents.

On April 26, officers allowed Boudreaux to leave the scene of the first accident he was involved in that day where he allegedly hit a car with two people inside, including a 2-year-old child.

Just hours later, Boudreaux allegedly struck a 61-year-old homeless man in the 4400 block of the Texas 5 Spur.

In a third incident that same day, a vehicle honked at Boudreaux after he allegedly passed out at a red light. Boudreaux then apparently woke up and ran a red light and hit a car with 6-year-old Joshua Medrano inside.

Medrano was taken to Texas Children's Hospital, where he died.

After the wrecks, Boudreaux was charged with two counts of Intoxicated Manslaughter, one count of Intoxicated Assault and Failure to Stop and Render Aid.

Boudreaux told officers at the time he was dealing with the stress of having a young son hospitalized since birth.

Since he latest arrest, Boudreaux has also been charged with Fraudulent Acquisition of a Controlled Substance.

After a reset hearing Monday, Boudreaux is due back in court August 26th on all five charges.
