HARRISONVILE, Mo. — The FBI increases the reward for information leading to the arrest of two escaped fugitives as the search grows.
The FBI is offering up to $10,000 in the case. The money is in addition to $5,000 that is being offered by the U.S. Marshals.
The FBI also added “wanted” pictures of the men to six billboards along I-435 and I-70.
The FBI warns the men should be considered armed and dangerous.
Sparks, 33, has blue eyes and weighs 185 pounds. He has a number of tattoos, including a full sleeves on both the arms.
A federal jury convicted Sparks of leading a criminal conspiracy linked to two
murders, multiple violent assaults, and distribution of narcotics.
Martinez, 43 has brown eyes and weighs 130 pounds. He also has several tattoos, according to the FBI.
He pled guilty in July to conspiracy to distribute methamphetamine and money laundering.
The FBI doesn’t think the two men are traveling together.
