Mom, 6-month old son shot in the head and left for dead in 1996. Police have yet to make an arrest in their murders.

A teenage mom and her 6-month-old son were found shot in their car in Stamford, Connecticut, in 1996.

Now, 25 years later, police have few clues on the person that pulled the trigger.

On Sept. 12, 1996, Rhonda and Coran Johnson were found fatally shot in her blue Toyota Camry, according to the Connecticut State Division of Criminal Justice.

Rhonda, 18, picked her son up from a babysitter’s home around 3:30 p.m. and was scheduled to work her shift as a dietary aide at Stamford Hospital at 4 p.m., police said.

But her family grew concerned when she did not show up for work and she didn’t contact anyone to say why. A passerby found Rhonda slumped over the wheel over her car around 8 p.m. Both Rhona and Coran were killed with gunshot wounds to the head.

In addition to working at the hospital, Rhonda was a part-time college student and graduate of Westhill High School in Stamford.

Stamford police Sgt. Anthony Lupinacci told The Hour he still believes the case is solvable. He said the original investigators worked around the clock and had a lead on a suspect. Lupinacci developed another suspect, though he declined to review further details with the publication.

With the passage of more than two decades, Lupinacci said he believes more people will come forward. He said Rhonda likely knew the killer and people likely know more than they have revealed.

Rhonda’s mother, Blanche Johnson, told The Hour she always felt people knew more than they were telling the authorities.

"Maybe people are afraid. I have no idea why this case hasn't been solved, or why people are holding back. I don't see how someone can murder two children and get away with it,” Blanche Johnson said.

Anyone with information on the Johnsons’ killings is asked to contact Stamford police at (866) 623-8058.
