Police have accused Angela Buchanan of tricking a woman into having a lesbian affair and marrying her.

The 30-year-old Buchanan of Lufkin, Texas has been charged with online impersonation and faces up to a year in jail.

Police allege that in a Yahoo! Messenger chat, Buchanan confided in her 51-year-old friend that Buchanan had had breast cancer in 2008 and that she was currently suffering from a pre-cancerous mass.

Later, Buchanan contacted her friend on Yahoo! Messenger, allegedly posing as a doctor.

The victim said “that 'Doc' advised that the pre-cancerous mass in Buchanan's breast could possible be delayed or cured by an increase in certain hormone productions,” the affidavit read. “'Doc' advised that this hormone production could be stimulated by sexual intercourse. 'Doc' began to recommend to [the victim] that she participate in sexual activity [with Buchanan] in order to bolster this hormone production and possibly save her friend's life.”

The victim said she decided to “make the sacrifice” to help her friend, despite her religious convictions.

Later, Buchanan convinced her friend to marry her in order to strengthen her claim in a child custody dispute, The Lufkin News reported. (It is not clear where the women married, as such unions are not legal in Texas.)

Buchanan's deceit came undone when the victim contacted Buchanan's former same-sex partner and found out that she had lied about having breast cancer in 2008 and that there was no ongoing child custody legal battle.

She later contacted the Lufkin doctor who had supposedly prescribed sex as a cancer remedy only to find out that her wife had invented the story.

Buchanan confessed her deception to police. She is currently free on bond pending future court dates.
