[UPDATED] Police: Sheriff's Deputy Slashed with Knife; Shoots Attacker

Updated at 2 p.m. Dec. 21:

A Will County Sheriff’s deputy shot a teenager who slashed her across the face as she and another officer responded to a domestic incident Thursday night, police said.

The teenager, 17-year-old Jose Chavez, was in critical condition Friday morning after undergoing surgery at Provena Saint Joseph Medical Center.

Spokeswoman Kathy Hoffmeyer said deputies responded to a home in the 2300 block of Gaylord Road around 7:25 p.m. after receiving a report of a subject with a knife.

Family members said Chavez was "acting erratically" and threateningly toward relatives at the home, according to Hoffmeyer. 

Relatives let deputies into the home, where they encountered the teen in a hallway, police said.

Hoffmeyer said Chavez refused to comply with deputies' orders to drop the knife and lunged at a female deputy, slashing her across the face.

"She discharged her weapon" in self defense, shooting the 17-year-old once in the chest, Hoffmeyer said. 

Police said the teenager was able to flee the home, but was subdued in the driveway by Crest Hill police who had also responded to the call, according to Hoffmeyer.

Both Chavez and the deputy, who has been with the sheriff's department for two years, underwent surgery Thursday night at St. Joe's. 

After undergoing a two-hour surgery to repair what Hoffmeyer described as a "serious laceration to her face," the deputy is expected to make a full recovery. Chavez remained in critical condition.

Deputy Chief Ken Kaupas said police have had prior contact with Chavez, "during which Chavez was a juvenile. Tonight’s behavior and attack may have been fueled by Chavez use of drugs earlier in the evening," Kaupas said Thursday.
