Officers said the gunman shot his fiance after a dispute.
When officers got to the scene, the suspect barricaded himself in an apartment unit and fired shots at them.
"I looked out the window and I saw the full SWAT team banging on my neighbor's door across the way for him to get out, so I knew it was real, so I got dress and got out," said Stephanie Brody, a neighboring resident who got evacuated.
Officers and SWAT team members were on scene for more than nine hours before the man surrendered to officers just before 2 p.m.
"The family contributed immensely. Despite the tremendous expertise of our people, it is amazing what will turn the key sometimes, so we are very appreciative," said Dep. Chief Kirk Albanese of the Los Angeles Police Department. "We use any tool in the toolbox to get it done. The last thing we want to use is force." The suspect now faces a list of charges including attempted murder.
Officials said that the woman was shot twice and was taken to a nearby hospital in critical but stable condition.
Several hundred people in the apartment complex had to be evacuated as officers dealt with the gunman.
