A robbery suspect arrested in a Spokane Valley water park after his truck ran out of gas reportedly told police he arranged to buy methamphetamine from the victim but robbed her instead.

Police found a pornographic video, a sex toy, condoms, syringes, plastic baggies along with the victim's backpack, according to court documents filed today.

Joseph W. Boyce, aka Joseph Davis, told detectives he's a meth addict with no money who threatened Jill Wick, 29, with a broken pellet gun before a friend, Jumah A. Robinson, 32, stole her backpack and purse in a parking lot at Trent and Argonne early Tuesday, according to court documents.

A K-9 helped police track Robinson and Boyce, 25, inside Splash Down Water Park after the men abandoned their 1998 Chevrolet pickup along eastbound Interstate 90. Police seized the pellet gun from the truck, along with two glass drug pipes, according to a search warrant.

Wick told police she met the men through her boyfriend and went to the Albertsons grocery store to give them a ride after they called her repeatedly. When she saw them in the truck, Wick said she asked "why they can't just drive that vehicle wherever they wanted to go," according to court documents.

Boyce is in jail on $50,000 bond; Robinson's bond is at $25,000. Both are charged with first-degree robbery.
