An undocumented immigrant is now facing charges of murder after authorities allege she fatally shot her partner and concealed the decaying corpse within a closet at a residence in Charlotte.

The Charlotte-Mecklenburg Police Department has reported the arrest of 23-year-old Lhis Birito Costa, who is accused of killing 26-year-old Evelin Carolina Enamorado-Cisnado.

The incident came to light when officers were dispatched to an apartment in eastern Charlotte for a welfare check, following a tip-off that suggested a possible death inside the property.

What initially appeared to be a simple welfare check rapidly escalated into a full-scale homicide investigation.

Upon entering the apartment, investigators reported finding Enamorado-Cisnado’s body concealed within a closet, obscured by a door and covered with multiple towels.

Detectives said the victim’s body had already begun decomposing.

According to court documents obtained by WCNC Charlotte, a DoorDash driver had arrived at the apartment and was told someone inside the home was dead, prompting the call to police.

The documents also state Costa told investigators she had been in a relationship with Enamorado-Cisnado and shot her after learning the victim was involved with someone else.

Police said Costa was located and arrested Wednesday in connection with the case. She was transported to the Charlotte-Mecklenburg Police Department’s Law Enforcement Center, where homicide detectives interviewed her.

Following the interview, Costa was transferred to the custody of the Mecklenburg County Sheriff’s Office and charged with murder.

During her first court appearance Thursday, a judge ordered Costa held without bond while the case moves forward.

The Mecklenburg County Sheriff’s Office confirmed Costa remains in custody at the county jail. Officials also confirmed that Immigration and Customs Enforcement has placed a detainer on Costa, meaning federal immigration authorities have requested notification before she is released.
