It was a particularly deadly weekend on Austin roads, with close to 50,000 extra people on the roads with the Republic of Texas Biker Rally at the Expo Center.
Three fatal motorcycle wrecks occured between Friday morning and Saturday night, and a hit and run accident Saturday night killed a pedestrian.
It also seems to be an upward trend, according to numbers from APD - 36 people have died on Austin roadways so far this year, compared to 20 at this point last year. Police point out that they don't see an overall pattern in the rise in fatal crashes.
