A man critically injured in a high-speed crash Friday night on the northwest side has died.

The victim was identified by the Bexar County medical examiner as 31-year Sergio Manzanilla.

Manzanilla crashed his car on I-10 near the La Cantera Parkway exit.

Police say he appeared to be speeding when he lost control, veered across the highway and slammed into a concrete pillar.

He was taken to University Hospital in critical condition, where he died.
