A Los Angeles County Sheriff's deputy swam into a lake to rescue a drowning teen, despite being nearly six months pregnant and off duty at the time.

Deputy Jenna Underwood-Nunez, a six-year veteran, was camping in the Silverwood area in the San Bernardino Mountains when she heard a distress call from a nearby lake.

After seeing splashing about 200 yards into the lake, she determined someone was drowning.

"Placing herself and her unborn child at potential risk out of concern for the life of a drowning person, Deputy Underwood-Nunez sprang into action and immediately ran toward the drowning victim to provide assistance," according to an LASD press release.

She swam toward the splashing while fully dressed and realized the screaming and splashing was coming from the brother of the drowning victim, who had passed out, slipped to the bottom of the lake, and was no longer breathing.

The deputy dove to the bottom, pulled the victim to the shore, and initiatived life-saving measures to restore breathing. 

After four cycles of CPR, the victim regained consciousness and was later airlifted to a local hospital. He was placed in the Intensive Care Unit and reached a stable condition. He's expected to make a full recovery. He is a 17-year-old Adelanto resident who is scheduled to graduate from high school in June.
