PHOENIX (AP) - Authorities say a Phoenix woman passed methamphetamine to four inmates by spraying a liquid form of it on paper.

Maricopa County Sheriff's detectives said Friday that 30-year-old Natasha Geach has been arrested on drug-related charges.

Detectives say they received information earlier this week that paperwork was being used to transport a spray form of meth.

They say a jailhouse conversation between Geach and an inmate also revealed similar details.

A search warrant was served at Geach's home.

Deputies say evidence there indicates she sprayed the liquid meth onto legal documents and then let them dry before mailing them.

A subsequent search of four cells turned up evidence and contraband.

The four inmates allegedly involved now likely face additional felony drug charges.

Authorities did not identify them.
