A Sacramento couple’s Reno vacation turned into a nightmare when their car was stolen and found at the bottom of the Sparks Marina. The couple left their Lexus with a valet at the Grand Sierra Resort on Friday. They were unable to find it anywhere the next morning. Meanwhile, Sparks police received reports of a submerged vehicle Friday at the Sparks Marina. Witnesses say a man described as Hispanic and between 20 and 30 years old ran away after pushing the stolen Lexus into the water. Both Sparks and Reno police are investigating the incident.  If you have any information, you’re asked to contact police.
