A mom has been charged with murdering her baby by deliberately leaving it for hours in a hot car in sweltering 95-degree Texas heat.

Vanessa Esquivel, 27, was arrested after her child died from being left in her car on Aug. 16 as the mom went to work in Frisco, police said.

“Detectives believe Esquivel intentionally left her 15-month-old child for over two hours in a vehicle she knew did not have working air conditioning with an outside temperature of at least 95 degrees,” the Frisco Police Department said.

Because her otherwise-unidentified baby died, “detectives believed probable cause existed that Esquivel had committed murder,” the department said.

Esquivel was arrested in Dallas on Aug. 20 and transferred back to the Frisco Police Department the same day. Cops did not elaborate on a motive.

She was booked at the Collin County Jail where she’s being held on a $250,000 bond.

If convicted, she faces five years to life in prison, according to police.
