Two men died in collisions while riding motorcycles in Prince George’s County on successive days this weekend: one Friday and the other Saturday.

Police said they were aware of nothing to indicate that either man was linked to the Rolling Thunder motorcycle rally held in Washington each Memorial Day weekend.

In Saturday’s crash, the motorcycle was traveling west on Central Avenue in the Capitol Heights area about 6 p.m. when it collided with a car turning left onto Cindy Lane from the eastbound lanes, said Cpl. Maria McKinney, a police spokeswoman. The name of the rider was not immediately available.

Police said that in Friday’s crash, Phillip Walker, 42, of Accokeek, was killed in Oxon Hill about 7 p.m. as he was riding north on Indian Head Highway.

Police said he apparently struck an SUV that was making a U-turn at Wilson Bridge Drive from southbound Indian Head.

A preliminary investigation showed that the driver of the SUV failed to yield the right of way, police said.

The motorcycle deaths were at least the second and third in the county in the past two months. A motorcyclist died April 6 in a collision in Fort Washington. That crash also occurred on Indian Head Highway.

Nationally, the number of fatal motorcycle crashes declined last year for only the second time since 1997, according to the Governors Highway Safety Association.
