The male victim murdered in Lincoln County earlier this week has been positively identified as an illegal immigrant from Mexico.
Investigators, in their search for the those who killed him, are following numerous leads in what has become an extensive investigation with ties to drug and possibly gang activity.
After releasing photographs of the victim's tattoos late last week, a witness came forward over the weekend and identified the decedent as 35-year-old Gustavo Barragan Valencia, investigators said.
His body was found in a rural area near Wellston on Wednesday.
Lincoln County Sheriff Charlie Dougherty said he was shot
"execution-style" and was found with a pillowcase over his head. His hands and ankles also were bound.
Dougherty, who held a press conference about the case on Sunday, said as part of the probe, they now know the identity of one of two persons of interests sought in a home invasion, which is believed to be related
to the homicide.
Authorities also are looking for the victim's cousin, who Dougherty said is also an illegal alien. Valenica worked as a landscaper and had reportedly been living in Oklahoma with his cousin since June, so they want to interview him although the sheriff said he is not a suspect in the murder.
Numerous law enforcement agencies are probing this case, which is believed to involve the homicide, as well as many other incidents attributed to a crime spree.
That spree includes the home invasion and a separate kidnapping case, with both of those occurring less than a mile from where the man's body was found inside Lincoln County on Pottawatomie Road near 960 Road, which is also N.E. 150th Street.
The sheriff said while they feel the crime spree and homicide are all connected in some way, they're still trying to piece them together with evidence.
Authorities will apply for search warrants Monday to check cell phones confiscated in this probe, the sheriff said, including one phone found about 10 feet from
the man's body. They also want to search at least two vehicles impounded during this investigation.
Watch for updates.
