STAFFORD, VA. — A Florida teenager accused of pretending to be a doctor faces new charges in Virginia after authorities say he fraudulently tried to buy a luxury car.

Malachi Love-Robinson was arrested Friday and charged with identity theft and other fraud offenses after he attempted to purchase a Jaguar at a car dealership, Stafford County Sheriff’s officials say.

They said employees at Kargar Motors Car Dealership became suspicious when Love-Robinson applied for a car loan with an elderly woman as the co-signer on the loan. The employees called the sheriff’s office after looking up Love-Robinson’s name in an Internet search.

Deputies came to the car dealership and spoke with Love-Robinson, who said he came to Virginia to buy a car for himself and another for his godmother.

Sheriff’s officials say they are still investigating, and Love-Robinson is being held in the Rappahannock Regional Jail.

Love-Robinson was arrested in February after law enforcement officials in Florida said he was practicing medicine without a license. Authorities in Palm Beach County said Love-Robinson was illegally operating a medical practice — complete with an office, a lab coat and stethoscope — but had no license to do so.

In one instance, they said he went to a woman’s house five times after she contacted him online to treat her for stomach pains. He told her she suffered from arthritis and sold her vitamins, charging her $3,494 that she paid by check.

Love-Robinson has denied the charges, saying he never said he was a medical doctor. He claims to have a doctorate from the Universal Life Church, which sells them online for $29.95.

His trial on charges of practicing medicine without a license has been delayed until November while his attorney considers a possible insanity defense, according to media reports.
