JACKSONVILLE, Fla. – The arrest warrant for a former Duval County School Police officer accused of engaging in a romantic relationship with a student is shedding more light on his alleged communications with students that investigators say led to his arrest.
Following a joint investigation by the Jacksonville Sheriff’s Office and Duval County School Police, Alexander Capasso, 26, was arrested on a warrant charging him with authority-figure soliciting or engaging in a romantic relationship with a student, unlawful use of a two-way communication device and tampering with evidence.

How the investigation began
According to the report, three students, ages 16 and 18, created a fake Instagram profile of a fictitious Mandarin High School student they named “Courtney” to see their ex-boyfriend’s posts.
They also posted a picture of an unknown 18-year-old girl smoking a cigarette.
According to the warrant, the students told police that Capasso, who was a school resource officer at their high school, messaged the fake account on Feb. 26, prompting a conversation to begin between the two accounts.
Investigators said Capasso told them about photography, his job and other interests, which led him to invite “Courtney” to hang out at a secret spot where he takes photos. He also advised them not to say anything about their interaction to anyone, according to police.
JSO said the victims running the account became uncomfortable with the conversation and blocked Capasso’s account.
Evidence allegedly deleted at school
On Feb. 27, Capasso somehow learned that the dean at the high school had questioned the three girls about the exchange on Instagram, so according to JSO, he pulled the girls from their classrooms and made them hand over their phones so he could permanently delete any screenshots of their conversations.
The students told police they felt intimidated by Capasso because of his position as a school police officer.
The report said the students told police that no inappropriate pictures were shared between them and Capasso, but they admitted that the conversation felt “inappropriate for someone working at the school.”
JSO: Another possible victim identified
As the investigation continued, JSO learned that another student, who attended the same high school but was separate from the three mentioned in the above incident, had also been in direct contact with Capasso on Instagram dating back as far as November 2025, according to the report.
The screenshots of the “romantic conversation” between the two included a comment by Capasso about choking, to which the student responded, “not complaining,” according to the report.
The report goes to say that Capasso replied, “I know you wouldn’t hahah.”
In another message, the student wrote, “gotta delete the chat again lordy,” and investigators say Capasso replied, “At least u remembered.”
The student previously worked at a gas station, where Capasso was caught on security footage visiting the student on Jan. 17, according to detectives.
Capasso’s interview with investigators
When detectives interviewed Capasso about the “Courtney” account encounter and the screenshots from the “romantic conversation” with the other student, he told police that he knew the account was fake and “merely wanted to see how far the conversation could go.”
According to the warrant, he also admitted to running the fake name through the law enforcement database called “Focus,” used by DCPS to search for student records. He told police that once he did not find any accounts matching that name for someone on Mandarin High School, he believed it was a fake account.
When asked about inviting “Courtney” to hang out despite knowing she was an 18-year-old high school student, he told police that he wanted to see if anyone would show up, the report said.
The warrant states Capasso also admitted to bringing the three students into his office and telling them to delete the messages but denied going through their phones and deleting the photos himself.
The report said he initially denied having any other outside interactions through Instagram or text messages with other students. When he was questioned about the screenshots of his messages with the second student, Capasso described the messages as “satire,” saying he did not “mean the things he wrote about choking her or trying to meet with her at a bar.”
The report said he also denied meeting any students outside of school but eventually acknowledged that he visited the second student at her job.
When detectives asked how Capasso would feel if his “high school daughter was messaging a school resource officer and he visited his daughters’ work, the report said he agreed those actions “seemed inappropriate.”
Capasso was arrested on Thursday on several charges, including engaging in a romantic relationship with a student, had worked on an interim basis at three Jacksonville-area high schools
Response from Duval County Schools
The district said Capasso submitted his resignation on March 2 while under investigation and was stripped of all law enforcement authority at that time.
DCPS told parents of the “serious matter” in a communication on Friday, saying Capasso, who began working for the district in October 2025, was not assigned to a specific school but worked on a rotating basis.
He most recently served on a brief, interim basis at Atlantic Coast, Fletcher, and Mandarin high schools, the district said.
