Doctors are split on whether a teen carjacking suspect accused of kidnapping a car seller with a fake gun and driving the bound man around Daly City while demanding his pink slip is mentally unfit for trial.

The unclear conclusion means a third doctor will decide if Jeremy Jenkins, 20, will be sent to a state mental facility for treatment rather than tried on charges of carjacking, kidnapping during a carjacking and second-degree robbery.

The third tie-breaking doctor's report is due Feb. 8.

Jenkins is accused of carjacking the seller of a Mustang after responding to the man's Craigslist in April. After returning to the Daly City BART station from the test drive, Jenkins allegedly pulled a replica handgun and ordered the 26-year-old man to handcuff himself. Jenkins pulled a pillowcase over the man's head and placed him in the back seat and demanded the pink slip, according to the District Attorney's Office.

When the man said the pink slip was at home, Jenkins allegedly drove around for 20 minutes before pulling into a garage and having the man call his mother. The woman, sensing something was amiss when asked to bring the pink slip to the BART station, called 911. The police waited at the BART parking lot and, when Jenkins arrived, detained him at gunpoint. After his arrest, Jenkins told authorities he made "a stupid mistake,” according to prosecutors.

Jenkins remains in custody without bail.
