Rock throwing warning signs up on I-35 as police investigate more incidents

The Austin Police Department is investigating two new cases of rock throwings on I-35. APD tells FOX  7 that one of them happened at 10:36 p.m. on June 6 on the Southbound side. The other one happened at 11:16 p.m. on the Northbound side.

Although they made an arrest last week in one case, police believe there is another suspect or suspects out there. There have been 85 cases since 2014. A major break has proved elusive.

Recently, in an email to FOX 7, officials announced the investigation would be turned over to APD's Organized Crime Unit. They say a formal announcement is expected in the coming days.

For the past several weeks FOX 7 has been asking TxDOT if it had plans to put signs up along I-35 to alert drivers about the rock throwings. In an email, a spokesperson said they did not.

FOX 7 also posed the question to Austin police. They said signs were needed. They added, although there has been intense media coverage locally, out of town drivers passing through may not know to be aware.

Austin police said they planned to go to TxDOT to ask them to reconsider putting signs up. Electronic signs did go up overnight on June 6 into early morning on June 7. They dot the North and South sides of I-35.

There is a $25,000 reward for the arrest and conviction of the person or people responsible.

Austin police have set up a dedicated line for tips: 512-974-7999. Tips can also be provided by downloading APD’s mobile app. Police are also urging any victims to call 911 immediately.
