Sheriff's officials said Ahmed and his partner were on patrol in the City Terrace area about 7:20 p.m. Tuesday when they noticed a person acting suspiciously in a car that was parked in a red zone.
When the two deputies approached the car, the suspect, identified by police as Nestor Torres, got out of the vehicle, struggled with Ahmed and then shot him in the face.
Then, Torres allegedly pointed the gun at Ahmed's partner, who was able to slap the gun away and fatally shoot the parolee.
Officials said Torres had two guns in his possession.
The second deputy was not shot but did receive minor injuries. Authorities say Torres, a reputed gang member, was pronounced dead at a hospital.
Torres' sister, Laura, spoke exclusively to Eyewitness News.
"I don't know how I'm going to get over this or how I'm going to move on with my life. It's my brother, it's just so unfair," she said. "I just saw him dead on the floor last night. I couldn't believe what just happened."
Laura Torres said she is so shaken by her brother's death that she may move to a different city.
Another family member said the 37-year-old father of three was struggling.
"People change when they are high on drugs and they become a different individual," said Lupe Andrade, another sister.
Andrade works as a counselor for troubled youth and said she is willing to help those who want to change their lives around. She said her brother did not have such a desire.
Torres' family members said their hearts go out to Ahmed's family, who were at his side at Los Angeles County USC Medical Center.
Hospital officials said the bullet was lodged in the right side of the deputy's face. There is concern that he may lose an eye.
Ahmed has been with the force since 2007 but has been in field training in recent months. The deputy who ultimately killed Torres was a 21-year veteran with the sherrif's department and was training Ahmed.
