TAMPA, Fla. (AP) - A Tampa couple is facing federal charges for an alleged bank-robbing spree that spanned two states.

The Tampa Tribune (http://bit.ly/196qXDe ) reports FBI agents arrested 28-year-old Immanuel Lee Williams and his wife, Cara Lee Williams, this week at their Tampa home. They're accused of robbing 13 banks in Florida and two in Alabama. Authorities say they used disguises and notes to demand money.

Federal investigators say the robberies took place between December 2012 and last month. Each suspect faces a maximum penalty of 20 years in federal prison.

Investigators say the robberies followed a pattern. The couple allegedly used gloves, afro-style wigs and demand notes written on yellow index cards.

Immanuel Lee Williams is being held without bail. A bond hearing for Cara Lee Williams is set for Thursday.
