SNOW HILL, MARYLAND — Two juveniles face criminal charges in connection with a shooting plot at Snow Hill Middle School, Worcester County officials said Friday.

Some details were announced during an afternoon news conference with officials from the Worcester County Sheriff's Office, Worcester County Public Schools and the Worcester County State's Attorney's Office.

Worcester Sheriff's Office Chief Deputy Mark Titanski, who led the news conference, noted that the available details were limited because of "the ongoing nature of the investigation."

The incident was first reported by Delmarva Now on April 5.

A brief timeline was outlined by the Worcester County Sheriff's Office as follows:

The incident was reported by students on March 22.

The Worcester County Sheriff's Office and the Worcester Bureau of Investigation started an investigation that day and learned of the existence of a school shooting plot.

By 4 a.m. Saturday, March 23, one juvenile had been detained in connection with the case.

By Monday, March 25, a second juvenile had been detained.

Worcester County Maryland Sheriff Matt Crisafulli described the actions of the eighth grade students who initially reported the threat to school administrators as "brave," calling them "true heroes."

"We are so grateful that what could have been a tremendous tragedy was prevented by the actions of the brave young eighth grade students who had the fortitude and courage to step forward and relay their concerns and fears," he said.

After the sheriff's office responded to the school and verified the threat was "credible," Crisafulli said the Worcester County Bureau of Investigation was called in to initiate an investigation. The bureau consists of members of the sheriff's office, Maryland State Police, Berlin Police Department and Pocomoke City Police Department.

Investigators worked through the night, he said, leading to one juvenile being detained early Saturday and another by Monday. Both have been charged with conspiracy to commit first-degree murder and other related charges.

"The investigation is still ongoing and has resulted in numerous interviews, search warrants, subpoenas and seizures on multiple pieces of evidence," Crisafulli said. "Evidence recovered from both suspects’ residences included materials referencing a prior nationally covered shooting event as well as plans relating to a school shooting at Snow Hill Middle School. Evidence recovered also revealed that this plot had been several months in the making."

Although the investigation is still continuing, he said that so far it has not revealed any indication that weapons or destructive devices were ever brought onto school property.

Both Crisafulli and Worcester Public Schools Superintendent Lou Taylor underscored in their remarks that they are confident there is no longer a threat to any Worcester schools.

Snow Hill is located about 25 miles from the resort town of Ocean City, Maryland, and about 140 miles from Washington, D.C.

"The Worcester County Sheriff's Office, Worcester County Bureau of Investigation, the Worcester County State's Attorney's Office and the Worcester County Public Schools are confident that due to combined efforts, there is currently no active threat to Snow Hill Middle School or any other school within Worcester County," Crisafulli said.

Taylor also emphasized that officials' first purpose was to honor the bravery of the students who came to school officials with information about the threat, preventing a potentially tragic event.

He urged the community to partner with officials on situations such as these because “speaking out with concerns or suspicions can be lifesaving.”

"While we acknowledge there is always more work to be done, I am proud to say that the system works," he said. "See something, hear something, say something — it truly works and our standing before you today is evidence of that."

The school system has also coordinated with local and regional agencies to make trauma counseling available to students and staff at both Snow Hill Middle and High schools. Taylor said anyone who has been touched by this incident is encouraged to take advantage of these resources.

While parents and community members took to social media to express frustrations about lack of information, Titanski closed the news conference by requesting the public respect the privacy of those involved in the investigation as "the challenges they face in coping with these events are significant."
