Elizabeth Antoinette Perez, 38, was found dead inside her car on June 13, 2016, on the northbound Interstate 15 onramp near El Norte Parkway in Escondido, California. Officers initially treated the scene as suspicious after noting a head injury and blood; it was later determined she died from a single gunshot wound to the head. The front driver and passenger windows of her car were shattered, and it was not clear whether she was killed inside the vehicle or elsewhere.

Investigators identified her boyfriend, Edward Andrew Long, as a person of interest after serving a search warrant at his residence. He was arrested in Las Vegas a little over a week after Perez’s body was found and was charged with first-degree murder. Law enforcement said the killing was premeditated; no motive was disclosed in the information released.

If anyone knew Elizabeth Perez, saw her or her car on June 13, 2016, or has information about her movements or about Edward Long around that time, please come forward.
