Fairfax County police believe an accused armed robber in jail may have plotted with his mother to kill a store clerk.
Marvin Enrique Marroquin robbed El Compadre Market in July 2017, police said.
He was arrested, and about a month later his mother allegedly showed up at the store. She told the victim not to proceed with the charges against her son, according to a warrant.
This July, El Compadre employees reported to police some suspicious activity at the store, including unknown men using cellphones to record the employees.
Police investigated and discovered a letter allegedly sent by Marlon Torres Bonegas, Marroquin’s cellmate, detailing payment for a murder.
Detectives then pulled the jail phone recordings and found several 3-way calls allegedly linking to a cellphone number belonging to Marroquin’s mother.
The conversations were about a female target at the store, police said. They discussed surveillance of the intended target, and getting photographs, work schedules and addresses.
