WESLACO – Federal agencies continue their investigation into the Austin bomber's hometown of Pflugerville, Texas.

Some in the Rio Grande Valley are finding ways to protect their packages and family who live in that town.

The packages that you bring into the United States Postal Service can be tracked, viewed and now have its picture taken before it comes to your home.

It's a safety feature called informed delivery.

"It can let people know what's coming through when it's coming through especially like with the bombing and all that up in Austin,” said Arnold Mata.

Mata said he's been concerned since the first bombing. His two sons live close to where the Austin serial bomber Mark Anthony Conditt's hometown.

In a press release issued to residents in Pflugerville, the authorities stated:

“Explosives experts from the Federal Bureau of Investigation (FBI) and from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are working to safely remove and dispose of homemade explosives located inside a house at 403 Second Street North, Pflugerville, Texas.

In an abundance of caution, Pflugerville Police and the Texas Department of Public Safety evacuated residents in a four-block radius – from North Railroad Avenue to City Park Road and north of West Pecan Street. Pflugerville City Hall is closed. Please stay clear of the area as agencies continue to work.

The FBI and ATF, in partnership with the Pflugerville Police Department, are working to mitigate any potential hazards to nearby residents.

This activity is related to the overall investigation of the Austin bombings.”

It’s the same town where federal agents found more explosive devices.

"Luckily he's not, he's like north Austin, south Pflugerville, hopefully, he's far away from that from that part of town so we're lucky about that,” said Mata.

Mata is also connected with mail delivery services.

He works with the Weslaco Independent School District and picks up mail and packages every day.

Mata wants to be more informed about the services. The post office website explained notifications are sent only on days when it's going to be delivered to the recipient's home and it's free.

Mata points out the new process will help calm fears about the bombings.

"Hopefully it's just something that's short-lived. It doesn't happen again,” said Mata.

He says the notification system is also an extra precaution; especially, when he sends packages to his sons who are caught in the middle of the chaos of the city.

The informed delivery service started in Dec. 2017. Many people have signed up and the service continues to grow.

The delivery service is available for eligible homeowners in a majority of zip codes. Postal service officials tell us they're still working to add more zip codes in their system.
