The driver, Mohammed Taqiuddin, 65, and his wife, Hussaina, 58, were both pronounced dead at the scene, said police.

A Lexington couple died in a single-car accident Saturday afternoon, and police are still investigating the cause of the crash.

At about 1:15 p.m., police and fire responded to Adams Street near Hathaway Road. The driver, Mohammed Taqiuddin, 65, and his wife, Hussaina, 58, were both pronounced dead at the scene, said Lt. Joseph O’Leary.

O’Leary said Taqiuddin’s car may have crossed to the wrong side of the street, traveled on the sidewalk and then smashed into a tree.

Police could not say if the couple were wearing seat belts. At this time, said O’Leary, speed and alcohol do not appear to be a factor.
