WICHITA, Kan. (AP) — At least 22 emergency 911 calls were made about what was happening in a Wichita home before a 2-year-old was found dead there and the toddler’s 4-month-old brother severely injured.

Wichita police found Zaiden Javonovich dead on April 11. Police say his body was facedown and bound in his crib.

The affidavit unsealed Thursday said Zaiden weighed just under 15 pounds and had cuts on his face consistent with someone pushing his head down into something. His baby brother had broken ribs and a bruised head.

Most of the calls came from Zaiden’s mother, 22-year-old Brandi Marchant, and his father, 28-year-old Patrick Javonovich. They are charged with felony murder and child abuse. But Zaiden’s grandmother also called seeking help for the children.
