SAN DIEGO — An investigation is underway after a man and woman were found dead Friday in an apartment complex in the Nestor area, the San Diego Police Department said.

Shortly after 11 a.m. police responded to a “report of death” call to an apartment complex in the 2300 block of Grove Avenue, Lt. Adam Sharki stated in a news release.

Upon arrival, police found the man and woman with apparent gunshot wounds, according to authorities. They were pronounced dead at the scene.

Sharki confirmed officers also discovered a firearm located inside the apartment.

Both of the victims, a 20-year-old Hispanic man and a Hispanic woman around 18 years of age, were not identified.

“Shortly after that, one of the male’s family members entered the apartment and discovered the two bodies. Multiple people then called the police,” Sharki said.
