SANTA FE — In the year since the shooting at Santa Fe High School, Sarah Salazar has fought high lead levels because of shotgun pellets left in her body.

Salazar, one of the 13 injured in the shooting, is going in for her eighth surgery since the shooting today in hopes of lowering those levels.

Salazar has 14 shotgun pellets still in her body, which has caused her high levels.

In a Facebook post this morning, Salazar’s mom said a group of surgeons will work to bring her lead levels down to normal.

“May God bless Sarah and the medical professionals working on her,” Sonia Lopez wrote on Facebook.

Previously, Salazar’s lead levels measured a 21. Doctors said normal levels are 5.

Prolonged exposure to lead can result in greater risks for high blood pressure, heart or kidney disease and reduced fertility, according to the Center for Disease Control and Prevention.

Ten people died in the shooting on May 18, 2018. A gunman walked into an art classroom and killed eight students and two teachers.
