The man charged with Sunday’s major interruption of GCI service across the state, remains in the Anchorage jail.

Brodie Eguires-Lee made his first court appearance late Monday afternoon.

Police say Eguires-Lee broke into the Denali Towers and GCI’s communications room Sunday morning and tore up the equipment inside. He also threatened an employee with a large screwdriver, prosecutors claim. That person ran out of the room and called police.

He called himself “Lucifer” to another employee, prosecutors said.

Police say they found Eguires-Lee incoherent, and claimed to work at GCI saying he was showing up to repair improperly set equipment that “would cause an explosion that could destroy half the vehicle.” Prosecutors said Eguires-Lee caused major problems. Damages worth millions of dollars, according to charging documents.

Eguires-Lee remains held on $25,000 bail. He could face up to 20 years in prison and a $250,000 fine if he is convicted.

Prior convictions include driving with a revoked license in Alaska, drug possession and domestic violence in Arizona.

He returns to court Tuesday afternoon.

GCI is the parent company of KTVA 11 News.
