"I had a backpack full of stuff," he said. "(I) hopped over her fence. Sat in a little area there by her green trash can."
While Action News cannot show Brambila's face, he broke down several times, overcome with emotion as attorneys pressed him about that day in 2020.
Prosecutors have charged the 59-year-old with four counts of assault, false imprisonment, and kidnapping. Brambila denies them all.
Action News cannot name the victim, but she taught Brambila music classes at Fresno City College and privately.
"I considered her a very good friend," Brambila said. "Over time, I developed feelings for her."
Hundreds of messages between the two were shown in court. Brambila repeatedly asked to meet in person, telling the jury on Wednesday that he was lonely amid the pandemic.
"The isolation was driving me nuts," he said. "I wasn't functioning. I wasn't going to school. I wanted to see her."
Investigators say Brambila went to his instructor's backyard in December 2020.
At one point, he wrapped his arm around the woman's neck while he had a gun.
Police recovered handcuffs, zip ties, chains, and padlocks.
Brambila insists he was not there to harm or kidnap his professor but admits the scene turned violent.
"After I bit her and she removed her mouth, she started gouging at my eye. My left eye. I grabbed her arm at that point to keep her from gouging at my face," he said.
The jury heard more testimony in the afternoon from character witnesses, potentially clearing the way for closing arguments and jury deliberations in the coming days.
