Former Oakland Raiders linebacker Thomas Howard was one of two people killed in a high-speed crash on Interstate Highway 880 early Monday morning, sources are telling KRON 4 News.

The incident was reported on Highway 880 south of Fifth Avenue at 12:50 a.m., CHP Officer Daniel Hill said.

Witnesses said the driver of a gray BMW 750Li sedan, identified as Howard, was driving north on the highway at more than 100 mph when he lost control and collided with the rear of a semi-truck in the left lane, according to the CHP.

The BMW launched into the air and crossed the center median onto southbound Highway 880, Hill said.

The BMW then struck a Chevrolet Monte Carlo and crashed into a gray Honda CR-V, he said. Officers found the BMW overturned in the southbound right lane and the Honda CR-V blocking the two southbound left lanes, he said.

The semi-truck was found in the northbound right lane north of crash site, according to the CHP.

The CHP and Oakland Fire Department personnel attempted to aid the drivers of the BMW and the Honda, but the extent of damage to the vehicles prevented responders from reaching the individuals, who both died at the scene, Hill said.

The driver of the Chevrolet sedan was transported to Kaiser Permanente Oakland Medical Center after complaining of pain, he said.

All lanes reopened at 5:30 a.m., according to the CHP.

The driver of the Honda was identified as a 55-year-old Hayward man, Hill said.
