CHARLESTON, W.Va. -- A Lincoln County woman could face a minimum of 32 years in prison after a federal grand jury indicted her Tuesday in the May armed robberies of a nursing home and a bank.

The grand jury in Charleston indicted Morgan Marie Mullins, 26, of West Hamlin, in the armed robberies of the Teays Valley Center nursing home in Hurricane on May 2 and the City National Bank in West Hamlin on May 22.

Police arrested Mullins on May 24 after bank employees recognized her voice during the armed robbery. Mullins admitted to police she used a 9 mm pistol and wore a mask to rob the bank of about $3,000, according to a criminal complaint filed in U.S. District Court in Charleston.

Mullins admitted she used the same gun to rob the nursing home of numerous prescription painkillers, according to a criminal complaint filed in Putnam County Magistrate Court.

Mullins had worked at the nursing home and broke in after hours on May 2 while wearing a clown mask, the criminal complaint said.

The grand jury also indicted Mullins with two counts of being an unlawful drug user in possession of a firearm. Mullins was under the influence of prescription medication at the time of the robberies, the indictment alleges.

Mullins faces a mandatory minimum of 32 years in prison, and could face life in prison and a $1.5 million fine if convicted on all charges.

The Federal Bureau of Investigation conducted the investigation. Assistant U.S. Attorney Steven Loew is in charge of the prosecution.
