TULSA, Oklahoma -- Two brothers are in critical condition at a Tulsa hospital after a motorcycle crash early Wednesday morning.
Tulsa Police say the crash happened on 31st Street between Sheridan and Yale just before 4:30 a.m.
Officers say the men were on a high performance motorcycle going over 100 miles an hour when the bike struck a concrete barrier.
Police say one brother wasn't wearing a helmet and has massive head trauma. The other lost part of his leg.
Tulsa Police say the driver of an SUV going the same direction swerved to try to avoid the crash, blowing out two of its tires in the process.
Shortly thereafter, police believe one or maybe two cars ran over the cyclist who lost his leg. Neither car stopped at the crash scene.
According to police the motorcycle traveled 650 feet after hitting the concrete barrier.
