This month will mark the second anniversary since a spate of rock-throwing incidents along Interstate 35 began. Here are five things to know so far:
1. Rewards total up to $25,000. The Greater Austin Crime Commission had offered a $10,000 reward in January, Gov. Greg Abbott’s office offered a reward of up $6,000 on Friday, and Austin Police Chief Art Acevedo said anonymous donors offered $4,000 on Sunday and $5,000 on Monday for information leading to an arrest.
3. No suspects, no arrests, but some patterns. An analysis by the American-Statesman found that many of the vehicles have been hit near overpasses, between 1 a.m. and 5 a.m., and most — nearly 70 of them — were heading north.
4. Solutions range from cameras to closures. Acevedo said confirming the use of police cameras earlier this year caused the attacker or attackers to change locations. Police also are looking at possibly shutting down I-35’s lower deck during the overnight hours when most rock-throwing incidents have been reported.
5. If you are hit, call police immediately. Don’t touch the rock or the area of impact. “Knowing the time and location of the rock throwing is very critical to our investigators,” police said in a recent statement.
