Berks County native on the front lines in Baltimore

Dustin Schappell has been a Baltimore city police officer for the last 18 years and he's been working round the clock during the protests, looting and rioting.

A state of emergency remains in effect in Baltimore.

Schools are closed, another Orioles game canceled and a city-wide curfew will go into effect at 10 p.m. Tuesday.

Crowds gathered Tuesday, but it was a much more calm scene than Monday. That is when the city saw looting, rioting and fires.

All of this, sparked by outrage over the death of Freddie Gray, a man who died after suffering a serious spinal injury while in police custody.

Hundreds of people were arrested and about 20 officers were hurt.

One officer on the front lines there grew up in Berks County.

Dustin Schappell has been a Baltimore city police officer for the last 18 years and he has been working round the clock during the protests, looting and rioting.

His sister, Tricia Wertz, who still lives in Berks County, says she never expected the peaceful protests to erupt into chaos.

"Once I saw them throwing the rocks and the bricks at the police officers and then the fires and them destroying the hoses to put out the fires and the looting and the rioting, it was just worry and anxiety," said Wertz.

Baltimore police say at least 20 officers were hurt in the riots. One is still in critical condition, but many refused to seek medical treatment because they did not want to get off the line.

Wertz said her brother Dustin is on the SWAT team and she is thankful he has not been injured.

"He just said the last week or so has been trying at best with the daily verbal and physical assaults on our officers. We will continue to hold the line and continue to be professionals until we restore order in our city," said Wertz.

Wertz is now praying for the safety of her brother and the other officers in Baltimore and says she hopes as a country we can learn from these events.

"We just saw Ferguson, now we see this. Just if anything, learn from the mistakes and just hope that it does not happen again," said Wertz.

Police say they have already made 200 arrests and plan to continue reviewing surveillance video and arresting people involved.

Police also say they will do whatever they can to mitigate future incidents.
