The Sacramento County Coroner's website notes that the six-year-old died at 1:45 a.m. Wednesday.
Henry and his brother, Juan Perez-Rocha, 8, were struck in a crosswalk Oct. 5 at Greenback Lane and Mariposa Avenue on their way to Skycrest Elementary in Citrus Heights.
Police said that a Chrysler 300 driven by Tresa Bales-Sterba, 52, of Orangevale collided with a Chevy Suburban in the intersection, then spun into the children. The boys' mother was walking behind her sons with another child and witnessed the accident.
The incident occurred just after 8 a.m. at what is described as a busy and dangerous intersection, where the speed limit is 40 mph but where drivers often speed more than 50 mph.
Hours after the collision, Citrus Heights police arrested Bales-Sterba on suspicion of felony driving under the influence with injury and misdemeanor driving with a suspended or revoked license.
She was released from the Sacramento County Jail after posting $100,000 bail. But during a later court appearance, the judge raised the bail to $200,000 after a toxicology report showed Bales Sterba was under the influence of methamphetamine and other drugs at the time of the crash.
The District Attorney's office filed a motion to increase bail based on the toxicology report and other factors.
Bales-Sterba was taken back into custody, but was released after posting the additional bail.
A check of jail records today does not indicate Bales-Sterba has been re-arrested on more serious charges.
Shelly Orio, spokeswoman for the Sacramento County District Attorney's Office, said staff
members will re-evaluate charges against Bales-Sterba once they have all the necessary information and reports.
Juan Perez-Rocha was sent home to recover not long after the collision that would eventually claim his brother's life. In mid-October, Henry was listed in critical condition at UC Davis Medical Center. His aunt told The Bee at the time that he was in a coma.
