Last night we told you about a Britton family who were offering a one thousand dollar reward to anyone that could help find the person responsible for hitting their son David Christenson with a car. After our story ran last night the family tells us people called them wanting to add more money to that reward. The family of fifty year old David Christenson are now offering two thousand dollars to anyone with information that leads to a conviction. Police say Christenson was hit by a vehicle Saturday night near Seventh Street in Britton and then the driver took off. Christenson is still recovering from a fractured skull and cracked ribs. If you have any information you are asked to call the Marshall County Sheriff's Department.
