It was Easter Sunday 1991.

18-year-old Bill Little had finished his dinner with his family before heading to his 3 p.m.

shift at the Clark gas station in Bloomington, Illinois.

Sundays at the station were usually quiet, but on Easter, the streets were even emptier.

As the hours passed, Bill worked the register alone, just like he always did on slow shifts.

Then, at 8.15 p.m., a silent alarm was triggered inside the store, and police were dispatched immediately.

An officer pulled up nearby and approached the station door.

He stepped inside and looked around,

and that's when he saw a single tennis shoe sticking out from behind the counter.

He took another step closer

and found Bill Little, lying motionless on the floor.

The register was open and the cash drawer was missing.

18-year-old Bill Little,

working a quiet holiday shift,

had been shot and killed for less than $93 in cash.

In the early 90s, there wasn't CCTV at every corner store and gas station, so finding a suspect

could often be more difficult. Detectives questioned men in the area with known criminal records,

but without any physical evidence to go on, they were at a standstill and the investigation went cold.

But more than eight years after the murder, an arrest was made, 25-year-old James Snow.

But the case against Snow wouldn't be built on DNA, fingerprints, or physical evidence.

It would be built on people, conversations, statements, and behavior that the prosecution

claimed linked Snow to this crime.
