NASHVILLE, TN (WSMV) -The case against the man accused of murdering a west Nashville gas station clerk is heading to a grand jury.

A hearing for Daniel Clark was held Thursday morning.

A detective was the only person who testified before the judge decided there was enough evidence to send this case to the grand jury.

Detective Tim Weaver with the Metro Nashville Police Department said Clark confessed to shooting John Stevens several times.

Clark reportedly told investigators he and 15-year-old Trinity Quinn intended to rob Stevens. They wanted his wallet, car keys and cellphone.

Police said surveillance video from the west Nashville gas station shows Clark shot Stevens 10 times when he wouldn't hand over his car keys. Two of those gun shots were to his head, and another two were to his heart.

When detectives asked Clark why he shot Stevens so many times, here's what he allegedly said.

"When he goes squirrel hunting, he always carries a pistol with him, so if he just injures the squirrel he can take it out of its misery," Stevens said.

Channel 4 also learned there was someone else inside the gas station during the shooting. The store manager was inside the bathroom, heard the gunshots and called 911.

Police originally issued an Amber Alert when Quinn left her Dayton home with Clark, but both were charged with murder after the killing in Nashville. Prosecutors want to try Quinn as an adult.
