DECEMBER 5--A Texas doctor involved in a love triangle broke into the Houston home of a romantic rival and scrawled the words “Whore” and “Homewrecker” in red lipstick on a bathroom mirror, cops allege.

Angela Siler-Fisher, 42, is facing misdemeanor harassment and trespassing charges stemming from her alleged break-in Sunday at the residence of Marcelle Mallery, a 35-year-old radiologist.

Siler-Fisher (seen at right) is a medical director at Houston’s Ben Taub General Hospital and teaches at the Baylor College of Medicine. Her husband Brandon, 43, is a radiologist.

According to a criminal complaint, Brandon Fisher called Mallery to warn that his wife “was coming to her house.” Mallery told cops that she was in fear for herself and her children, so she fled the residence.

Mallery told investigators that she received two phone calls from Siler-Fisher as she was en route to the home. Siler-Fisher, Mallery said, warned that she “was going to beat her fucking ass whore” and “dislocate her vagina.”

Surveillance videos revealed that Siler-Fisher entered Mallery’s home by “kicking in the doggy door.” Once inside the sprawling home, she wrote “Whore” and “Homewrecker” in red lipstick on a bathroom mirror. Pictured at left, Mallery told police that Siler-Fischer texted her a photo showing Mallery’s bedroom.

Police also report that Siler-Fisher left unused condoms on each step of a stairway inside Mallery’s home.

Siler-Fisher is scheduled to be arraigned in Harris County District Court on December 11. (2 pages)
