Two teenagers are accused of fatally stabbing a 19-year-old woman after the dying victim identified them to California police on her deathbed Monday, PEOPLE confirms.

On Tuesday, police recently identified Lizette Cuesta as the woman who was left for dead outside Livermore, California, according to a press release from the Alameda County Sheriff’s Office. She was from nearby Tracy.

Before she died, Cuesta sustained stab wounds and several other unspecified injuries, the release states.

Police also identified the murder suspects as 19-year-old Daniel Gross and Melissa Leonardo, who is 25.

The relationship between the two defendants is unclear at this time, but investigators described Gross and Leonardo as Cuesta’s friends.

They were arrested in Modesto on Monday, hours after Cuesta “was able to provide us with pertinent information about her attackers,” reads the statement.

It was unclear Wednesday if Gross and Leonardo, both charged with murder, had entered pleas. PEOPLE was unable to determine who their attorneys were.

Dispatchers received a 911 call about 2 a.m. on Monday about a woman lying in the middle of the street, the release states, adding that the caller believed she only had one arm. Police found a woman with two arms bleeding severely at the described location.

Cuesta was airlifted to Eden Medical Center in Castro Valley, where she told police what happened.

According to police, Cuesta crawled nearly 100 yards along the roadway before being discovered by the caller, a passing motorist.

Detectives have yet to determine a motive for the killing.

Dying declarations are rare. Legal experts say they are the strongest evidence one can present during a prosecution.
