A North Fort Myers teen arrested in connection with the shooting death of Kayla Rincon-Miller is now facing additional charges and has been charged as an adult.

The State Attorney’s Office on Monday “direct filed” its case against Thomas Roy Stein, 16, placing him the adult criminal justice system. He has been be transferred to adult custody where he will remain as his case is adjudicated, officials said.

Stein was arrested on March 19 and charged as a principal to a murder while engaged in a robbery. Additional charges were added Wednesday when he appeared in adult court: one count of homicide without premeditation and three counts of robbery with a firearm, according to jail records.

Kayla, 15, was walking with two friends, heading to get something to eat after seeing a movie at the Coralwood Mall at around 9:40 p.m. on March 17. A car pulled up behind them, blinded the girls with its headlights, and an occupant or occupants jumped out and tried to rob the girls before one fired, striking Kayla in the chest, CCPD officials have said.

Stein was first charged as a “principal” because he was “engaged in the attempt of a robbery and (his) accomplice caused the death of the victim,” the CCPD arrest report states, adding Kayla was shot by someone else.

The CCPD has asked that anyone with information regarding the shooting, or anyone with any surveillance videos, to call the department at 239-574-3223 or Crime Stoppers at 1-800-780-TIPS (8477
