A 58-year-old surgeon has pleaded guilty to felony charges stemming from her brutal attack on a court-appointed child-custody supervisor while attempting to kidnap her then-12-year-old son in Goleta in 2019.

Dr. Theresa Lynn Colosi of San Jose entered the plea April 7 under an agreement with the Santa Barbara County District Attorney’s Office.

Colosi admitted a single count of assault with a deadly weapon, along with a criminal enhancement for causing great bodily injury to her victim, according to Deputy District Attorney Heather Trapnell.

Under the plea deal, Colosi will be sentenced to five years behind bars — two years for the assault charge and three years for causing serious injury to the child-custody supervisor, Cindy Hann, Trapnell told Noozhawk.

Three other charges — attempted murder, attempted kidnapping and disobeying a domestic-violence court order — were dropped as part of the plea agreement, Trapnell said.

An orthopedic surgeon who had been practicing in the Bay Area, Colosi was accused of assaulting and seriously injuring Hann on Dec. 8, 2019, during a court-ordered supervised visit with her son, who has not been named in court documents.

The attack occurred in the parking lot at Zodo’s Bowling & Beyond — now Bowlero — at 5925 Calle Real in Goleta.

The Santa Barbara County Sheriff’s Office alleged that Colosi began acting suspiciously while walking with her son, which caught Hann’s attention.

Colosi then swung a metal compressed-CO2 gas canister at Hann, hitting her in the head several times.

Hann told the boy to run into the bowling alley for help, and Colosi began following him, but then ran to her vehicle and fled the area.

Detectives discovered that Colosi had chartered a private jet that took her from the Lompoc Airport to Glacier International Airport near Kalispell, Montana.

Detectives also learned that, before the incident at Zodo’s, Colosi gave away her belongings, withdrew $900,000 from her bank account, and chartered the flight with fictitious names for herself, her son and her dog, according to the Sheriff’s Office.

Colosi eventually was arrested in Montana by officers of the Whitefish Police Department, and was extradited back to Santa Barbara County on Dec. 19, 2019.

She has been held without bail since then at the Santa Barbara County Jail.

The plea agreement was reached just as jury selection was about to begin for Colosi’s trial before Superior Court Judge Michael Carrozzo.

In explaining why prosecutors were willing to drop some charges, Trapnell said they were concerned that it could have been difficult to convict Colosi on the attempted-murder charge because they would have had to prove she intended to kill Hann as opposed to disabling her.

“We would have to convince 12 jurors of the specific intent to kill,” Trapnell said. “Even if you know that what you do could kill somebody, we would have to prove a specific attempt to kill that person.”

Trapnell added that conviction on the attempted-kidnapping charge would have added only one additional year to Colosi’s sentence.

Colosi will be given credit for time served in custody, Trapnell said, meaning she likely will be paroled in March 2024.

Still to be decided are fines and restitution that Colosi will face as a result of her crimes, which will be decided at sentencing.

Colosi is due to return to court on May 22, at which point a sentencing date will be set.

It has not yet been determined whether Colosi will serve the remainder of her sentence in state prison or the County Jail, Trapnell said.

Protective orders for both Hann and the boy were filed against Colosi after the attack. They remain in force, Trapnell said, and are expected to be renewed at sentencing.

In the wake of the attack, Hann filed a civil lawsuit against Colosi in June 2020, asserting that her life was shattered by the incident.

In the lawsuit, filed by Santa Barbara attorney Patrick McCarthy, Hann has requested a jury trial, and is seeking an undetermined sum of money, for both actual and punitive damages, after enduring “physical pain, physical injuries, facial scarring, emotional distress, mental suffering and lost earnings.”

Colosi has not responded to the lawsuit, McCarthy said, and has not hired an attorney to represent her in the case.

“Basically, Colosi defaulted on it,” he added.

Hann is still dealing with the impacts of the traumatic incident, McCarthy said.

“In the big picture, she’s physically doing well,” he told Noozhawk this week. “But she’s still grappling with the emotional part of it. She doesn’t understand why it happened.”

Colosi also is a defendant in a civil action filed by Montecito Bank & Trust last November, according to Superior Court records.

When she liquidated her accounts, Colosi reportedly turned the money into cashier’s checks, and the bank has asked the court to decide who has a legal right to those funds.

Colosi reportedly owes as much as $500,000 in back child support in the Bay Area, and her son’s biological father is seeking access to the funds, according to McCarthy.

Hann and the biological father also are named as defendants in the bank’s legal action.

The Medical Board of California in December filed an action to revoke Colosi’s medical licenses based on the attack and kidnapping attempt.

Thus far, no hearing has been held on the matter.
