SAN ANTONIO – The trail ended with the arrest of Jerry Idrogo Friday in Ohio, but it began in San Antonio - and before Balcones Heights police Officer Julian Pesina was murdered.
A murder warrant for Idrogo, 33, was issued Thursday. That sparked a cross-country, multi-agency search that began with the Bexar County Sheriff's Office Fugitive Apprehension Unit.
"We began using all available resources in the best places to try to track him down," said Tammy Burr, deputy chief of the Judicial and Court Services Division of the Bexar County Sheriff's Office. "We contacted the right people who finally broke and told us his whereabouts."
The Sheriff's Office passed the information to the San Antonio Police Department and the FBI who traced Idrogo to his grandmother's Toledo, Ohio, home where he was arrested. But investigators had already started connecting the dots between Pesina and Idrogo, though they may not have known it at the time.
According to the arrest affidavit, on May 1, three days before the murder, law enforcement agents obtained and executed a search warrant at Idrogo's last known address - a home in the 1800 block of West Travis Street. Inside investigators found a ledger with Pesina's name, address, phone number and nickname under the heading "North Roster." The affidavit says the roster listed persons with ties to the Mexican Mafia.
ABC News Crime Expert Brad Garrett said the ledger is a pivotal piece of evidence that could not only give investigators insight into the crime, but also additional information about the Mexican Mafia.
"Potentially it's a fantastic piece of evidence because in addition to being linked to the office, who else is in the network?" Garrett said. "Does it come back to other players known to the narcotics detectives and DEA, or does it even come back to other officers in the department?"
Garrett said Idrogo could also offer up valuable information to law enforcement once he is extradited from Cleveland back to San Antonio.
