Investigators say threatening emails, internet records and a law-enforcement-themed social media account led them to a 38-year-old suspect.
DORAL, FL — A Central Florida man is facing two felony charges after investigators accused him of sending threatening emails to Miami-Dade Sheriff Rosie Cordero-Stutz, including one that referred to bombing a school and another that threatened the sheriff and her family, according to court records.
Julio Javier Landaeta, 38, of Kissimmee, was arrested after Miami-Dade sheriff’s investigators traced the messages through electronic records to accounts and an internet connection they said were associated with him. Investigators also found a social media account they believed belonged to Landaeta that contained photographs of Cordero-Stutz and other law enforcement personnel, along with images that appeared to show Landaeta dressed in police-style clothing and equipment.
The investigation began Nov. 2, when an email arrived at the sheriff’s publicly listed government address at 3:21 p.m., according to an arrest warrant. The subject line contained profanity and a statement about bombing a school. Investigators said the body of the message included screenshots related to subjects such as credit monitoring, diplomatic immunity and the World Health Organization. The warrant said the message did not identify a school, location or time for any threatened attack.
A second email was sent from the same account about 90 minutes later, investigators said. Its subject line contained threats against the sheriff and her family and referred to Russian President Vladimir Putin. The email also included an image of Landaeta’s Florida driver’s license, according to the warrant. Investigators said the license photograph helped them compare the sender with an Instagram account they later examined.
Detectives said that Instagram account used a handle that included Landaeta’s name and the word “sheriff.” The account contained numerous photographs of Cordero-Stutz, Miami-Dade Sheriff’s Office personnel and other law enforcement agencies, according to the warrant. Other images appeared to show Landaeta wearing a dark polo shirt and tactical vest bearing law enforcement insignia. Investigators said he also appeared to be wearing a duty belt holding what looked like a firearm, a Taser, a radio and a flashlight.
Those images prompted descriptions in some reports that Landaeta had posed as a law enforcement officer. The records reviewed for the threat case, however, list charges tied to the alleged written threats rather than a separate charge of impersonating an officer. The social media images and police-style equipment were described by investigators as part of the background investigation into the threatening messages.
Investigators sought emergency information from Google and obtained subscriber and internet protocol records connected to the email account. Authorities said those records linked the account to a cellphone associated with Landaeta and to a business internet connection at an extended-stay hotel in Kissimmee. Florida Department of Law Enforcement agents went to the hotel on the night the emails were sent and located Landaeta in a room, according to the warrant.
A warrant issued Nov. 4 charged Landaeta with two second-degree felonies. Court records identify the allegations as a written threat to kill or cause bodily injury and a written threat involving a mass shooting or act of terrorism. He was taken into custody in Osceola County before being transferred to Miami-Dade County to face the charges.
A Miami-Dade judge set a total bond of $30,000, with $15,000 attached to each count. Court records show that if Landaeta is released, he would be subject to house arrest and GPS monitoring. He was also ordered not to contact Cordero-Stutz and to stay away from her home and workplace. A public defender entered a written plea of not guilty on Landaeta’s behalf Thursday, waived formal arraignment and requested a jury trial.
Cordero-Stutz became Miami-Dade County’s first female sheriff when she took office in January 2025 as the county returned to an elected sheriff system. She had previously spent nearly three decades with the Miami-Dade Police Department and held several senior positions before becoming sheriff.
As of the latest available court and detention information, Landaeta remained in custody in Miami-Dade County. The charges are allegations, and the case has not been adjudicated. Authorities have not announced evidence that a particular school was selected as a target or that a specific school bombing plan existed beyond the language contained in the email.
