A second body has been pulled from the site of Saturday's deadly building explosion in Borough Park and could be a tenant who remains missing. 

The unidentified body was pulled from the rubble Monday afternoon, according to fire officials, bringing the death toll to two. 

Ligia Puello, 64, who lived on the third floor of the building on 13th Avenue near 42nd Street, was discovered on the day of the explosion, Saturday. Officials said Puello was killed as she walked on the stairwell not far from the source of the fire. She was pronounced dead at the scene and identified on Sunday. 

Officials said one person was also reported with severe injuries, one with moderate injuries and 10 with minor.

But another person, 46-year-old Franchezka Figueroa, has remained missing, according to media reports. She was reportedly moving out of her apartment after she was supposed to have been evicted earlier in the week. 

Investigators believe the explosion was caused by a gas leak after residents on the second floor moved out and took a gas stove they bought with them.

FDNY Commissioner Daniel Nigro told reporters on Saturday the former tenants might not have shut off the gas line after removing the stove.

WABC reported that Figuerora was the tenant and planned to take the stove with her. There are also media reports of Figueroa posting suicidal thoughts on social media, but her family says suicide is not the cause, according to CBS New York.

"Her car was here, her phone was here," Councilman Brad Lander, who has been in close contact withe the family told WABC said. "One of her relatives spoke with her in the building somewhat earlier in the day, and they haven't hear from her since then."
