Authorities launched a dragnet Sunday for three South Carolina inmates, including two who were charged with murder, after they escaped prison, the sheriff’s office said.

Tyshon Demontrea Johnson, 27, Curtis Ray Green, 20, and Christopher Shannon Boltin, 27, escaped from Orangeburg County Detention Center Saturday night, the sheriff’s office said in a Facebook post.

Investigators discovered they were missing after they were notified of a possible escape attempt just before 10 p.m.

Authorities said the three inmates are considered dangerous. Johnson and Green were charged with murder while Boltin faces carjacking and grand larceny charges.

Other inmates who possibly helped the inmates escape are being questioned.

The sheriff’s office urged anyone with information on the suspects or incidents to call Orange County Sheriff’s Office at 803-534-3550 or Crimestoppers at 1-888-CRIME-SC.

A manhunt is underway in Maryland after "multiple" people were discovered fatally shot inside a Brookville home on Monday afternoon.

Montgomery County Police, who did not initially name the suspect, tweeted that the department responded to a domestic disturbance call following a "report of multiple people shot inside." 

There were "multiple fatalities" inside the home roughly 16 miles west of Gaithersburg, police said. It was not immediately clear how many people were found dead.

The suspect — who's believed to be known by police — is not in custody. Police said they "do not believe this was random."

People who live in the area have been warned to "shelter in place." Police will provide updates as the manhunt continues.
