An O.C. woman accused of murdering her husband and attempting to kill her two sons is facing new charges.

Annamaria Gana ,41, is already in jail. Investigators said she shot and killed her 72-year-old husband Antonio Potenciano Gana in their home in May. Authorities said she then shot her 16-year-old son in the arm before her 9-year-old son wrestled the gun from her.

The 9-year-old was not injured.

Prosecutors filed additional charges Tuesday, including a special circumstance of lying in wait.

If convicted, she could get life in prison without parole.

Officials said Antonio Gana was a retired colonel from the Philippines and a former general manager of the Manila International Airport.

Friends said the couple owned a small business in Orange and that Annamaria Ganahad undergone a double mastectomy, chemotherapy and radiation after being diagnosed with breast cancer last fall.
