Seahawks' top wide receiver Doug Baldwin sent a message to President Donald Trump and others who reacted on Twitter after a mass shooting at a high school left 17 dead in his home state of Florida.

“WAKEUP!!!!”

Officials say the shooter was a 19-year-old student who had been expelled for disciplinary reasons from Marjory Stoneman Douglas High School, which has about 3,000 students, in the city of Parkland.

"This is just absolutely pure evil," Florida Gov. Rick Scott said Wednesday night.

The suspect was taken into custody without a fight about an hour later in a residential neighborhood about a mile away. He had multiple magazines of ammunition, authorities said.

Baldwin has strong family ties with police. Baldwin's father, Doug Baldwin Sr., is a retired police officer who served 35 years with the Pensacola Police Department and ran for Escambia County Sheriff as a Republican.

He has spoken publicly about police issues in the past. In 2016, he met with Seattle police to discuss the state of law enforcement, and had called on all 50 state attorneys general to review law enforcement training,
