A California man was sentenced to at least 32 years in prison on Tuesday for the 2014 death of his girlfriend’s 18-month-old son—who paramedics found unresponsive and covered in human bite marks.
Left to care for Dante Nava as his mother worked, Marco Antonio Alvarado-Cisneros, 27, called 911 on August 12, 2014, and reported that the toddler wasn’t breathing and was unconscious. Though he claimed Nava possibly fell off the bed and suffered a seizure, an autopsy revealed that Nava had brain and eye hemorrhaging, bruising in various stages of healing, and a “massive subdural hematoma.”
The little boy also had human bite marks from an adult, according to the Daily Post.
Nava’s mother was initially uncooperative with the criminal investigation. She continued to live with Alvarado-Cisneros and had a child with him in May 2015. Around a year later, she revealed that he abused her, robbed her, and kidnapped her, according to KPIX.
Alvarado-Cisneros was arrested in September 2015, following a year-long investigation. He was convicted in April of involuntary manslaughter and assault on a child causing death.
According to the Daily Post, District Attorney Steve Wagstaffe described him as having “zero reaction, totally flat” as the jury handed down guilty verdicts.
