A motorcycle crash killed two people Sunday afternoon, and police suspect it is rain related.

The man and woman took the ramp from I-37 to 410 around 2:30 Sunday.

Police think the man lost control of the bike on the rain slick roadway.

The bike skidded and tossed both riders.

Both died on scene.

Police say both were wearing helmets, but suffered fatal injuries.

The riders names have not yet been released.

Police say the couple was coming from Corpus Christi to San Antonio.
