Federal authorities have charged two individuals in connection with a targeted attack on a Texas ICE detention facility earlier this month that left one officer injured as the final suspect remains on the run. 

John Phillip Thomas and Lynette Read Sharp are charged with alleged accessory after the fact in the July 4 shooting at the Prairieland Detention Center in Alvarado, according to court documents. 

“[Sharp and Thomas] were involved in Signal Chats, which show reconnaissance,” Nancy Larson, the acting U.S. Attorney, told “Fox and Friends” on Tuesday, adding the pair are accused of “planning a Google map [and] the location of nearby police departments.” 

Authorities are still searching for alleged attacker Benjamin Hanil Song. Song, 32, is wanted for his involvement in what officials say was an organized attack on ICE officials by a group of 10 to 12 individuals.

“We believe he is somewhere in the Dallas-Fort Worth area but have expanded our publicity efforts to neighboring states just in case,” the FBI Dallas Field Office told Fox News Digital on Monday. 

Song is accused of firing two AR-15-style rifles at a pair of correctional officers and an Alvarado police officer, according to a criminal complaint. He faces three counts of attempted murder of a federal officer and three counts of discharging a firearm in furtherance of a crime of violence. 

The FBI did not immediately respond to Fox News Digital’s request for comment. 

The FBI is offering a $25,000 reward for information leading to Song’s arrest and conviction, with authorities noting the former U.S. Marine Corps reservist should be considered armed and dangerous. 

“These latest two charges show the walls are closing in on [Song],” Larson said, adding, “he is running out of people to go to.”
