SANTA ANA (CBS) — A 44-year-old Garden Grove man pleaded guilty to beating and strangling his ex-girlfriend to death and was sentenced Friday to 15 years to life in prison, according to a prosecutor.

Arturo Tapia Salazar killed 52-year-old Cristina Ramirez, the mother of his young daughter, on Oct. 15, 2010, when she came over to Salazar’s apartment and got into an argument with him over child support, Deputy District Attorney Cameron Talley said.
