A Coral Gables man awaiting trial for the DUI hit-and-run crash that killed a 13-year-old girl was re-jailed Friday after he tested positive for amphetamines.

Sandor Guillen had been on house arrest and was ordered not to drink alcohol or take drugs. He is accused of DUI manslaughter in the April 13 wreck that killed Kaely Camacho, who was riding in her family’s mini-van.

Guillen kept driving, then tried staggering away from his mangled vehicle on foot, according to police. He told Miami-Dade Circuit Judge Ellen Sue Venzer that the drug was Adderall, for which he had a prescription for attention deficit disorder.

But Guillen could not initially name who prescribed him the medication, and the judge could not get through to the doctor. He’ll be allowed back out on bond if he shows his prescription Monday.
