ST. LOUIS • Prosecutors filed 10 felony counts Thursday against a St. Louis man, accusing him of posting online threats that included the killing of St. Louis police.
Each count accuses Jason Valentine, 35, of making a terrorist threat, a Class C felony, which has a maximum penalty of seven years in prison.
The accusations claim that on various dates between Dec. 3 and Dec. 14, he used the social media site Twitter to threaten an explosion at the St. Louis Justice Center downtown and to threaten the lives of police.
A police source says the department stepped up efforts to identify Valentine after two police officers were killed in New York on Dec. 20.
Since their deaths, police departments from across the country contacted St. Louis police to warn them of Valentine’s tweets, the source said.
Valentine, who lives in the 4200 block of Castleman Avenue in St. Louis, is in custody. Cash-only bail was set at $100,000.
The messages he allegedly posted made reference to Ferguson, where the shooting of Michael Brown by police Aug. 9 stirred a national controversy, and to the subsequent killing of Vonderrit Myers Jr. in a confrontation with a St. Louis officer in the Shaw neighborhood.
The circuit attorney’s office said the Twitter postings were made under the name “@jdstl314,” and that Valentine admitted being the only person to use it.
Police say he posted at least nine threats to kill St. Louis police officers, and used the slang “pig” and “12” to describe police officers. He also posted “211MOB” in some of his tweets, which is believed to be gang-related, according to court documents.
According to the documents, Valentine’s alleged tweets included a reference to “Kill a pig night,” and made specific references to killing former Ferguson police officer Darren Wilson for money and St. Louis Police Officers’ Association Business Manager Jeff Roorda.
The posts also included threats to kill black police officers, using the term “Uncle Tom,” according to the documents.
Twitter suspended Valentine’s account Monday.
In 2012, Valentine was charged with aggravated stalking and violation of an order of protection order, according to court documents.
