A deadly house fire in Hollywood has left two elderly sisters dead, their family home destroyed, and a neighborhood shaken — as prosecutors accuse a serial arsonist of setting the blaze.

Authorities say the suspect is responsible not only for the fire that killed the women but also for a string of other fires across the area.

The tragedy unfolded in the early morning hours of Feb. 4 at a longtime family home on Vista Del Mar Avenue near West Yucca Street in Hollywood, according to the Los Angeles County District Attorney’s Office.

As flames engulfed the home, one of the sisters, Maria Del Consuelo Alarcon-Valdez, 76, was briefly seen on the front porch, desperately calling out to a neighbor.

“I need to go back and get my sister,” she reportedly said, referring to her older sibling, Yolanda Honda, 82.

Moments later, both women were trapped inside the burning house.

When firefighters arrived at the scene, they found the sisters inside the home, according to local reports.

Alarcon-Valdez died at the scene. Honda was rushed to the hospital but later succumbed to her injuries.

Later that same day, authorities arrested 39-year-old Jovan Lamar Duverne in connection with the deadly blaze.

Prosecutors allege Duverne is a serial arsonist who set a series of fires throughout Hollywood between Jan. 26 and Feb. 4.

On March 11, the Los Angeles County District Attorney’s Office announced that Duverne had been formally charged with two counts of murder and 11 counts of felony arson.

The charges stem from the fire that killed the sisters and from at least 10 other suspected arson incidents in the neighborhood.

Investigators believe Duverne used a handheld torch-style lighter to ignite rubbish and other materials before moving from location to location, allegedly attempting to set additional fires and enter buildings.

Prosecutors say he walked between different locations during the alleged crime spree, leaving a trail of small fires behind him.

Duverne is also facing a special circumstance allegation for multiple murders, along with sentence enhancements tied to a previous arson conviction.

Those enhancements include a second-strike allegation that could significantly increase his sentence if he is convicted.

He is currently being held without bail.

If convicted on all charges, Duverne could face the death penalty.

As the criminal case moves forward, the victims’ family continues to mourn the devastating loss of the two sisters who had spent decades living in the Hollywood home.

Alarcon-Valdez, known affectionately as “Chelo” to family and friends, had recently been recovering from emergency hip surgery following a fall.

According to a fundraising page created by the family, the injury had occurred after what they described as an incident involving supermarket negligence.

During her recovery, Honda — known as “Yola” — moved into the home to care for her sister full time.

Family members said Honda stepped in without hesitation, ensuring Chelo was safe, fed, and supported during her recovery.

In the wake of the fire, the family has also been desperately searching for another member of the household — Chelo’s beloved dog, Coco.

Coco disappeared during the fire and has not been found.

The dog is microchipped, and family members have been searching shelters, posting flyers throughout the neighborhood, and sharing alerts online in hopes that someone might spot her.

Fire officials believe the dog may have escaped during the chaos of the blaze.

For the grieving family, finding Coco would offer one small piece of hope after a devastating loss.
