A man on trial for assaulting a St. Paul police officer three years ago was convicted on all counts Friday evening.

Thomas Jerard Swenson, 35, was found guilty by a Ramsey County District Court jury of two charges of assault and a charge of obstructing legal process.

Swenson assaulted officer Felicia Dee Reilly, now 56, when Reilly responded to a 911 hang-up at his parents’ home in March 2010.

Reilly had testified that Thomas Swenson was angry from the minute she walked in the door, and that he punched and kicked her to the point where she thought she was going to die.

Reilly suffered head injuries, and — three years after the incident — sees double, has nearly constant migraine headaches and can’t stand sound and light, she testified. She also has memory problems, she said. After she was unable to work on light duty, she receives disability benefits from the Minnesota Public Employees Retirement Association, she said.

Unmentioned at trial, Reilly has been fighting the city for worker compensation benefits.

“I’m very glad that justice was served today. It’s time to let the healing begin,” Reilly’s son, Ben Reilly, said after the verdict was read.

Swenson’s parents, who testified on his behalf as the trial wrapped up Friday afternoon, were not present for the late-evening verdict, which was reached after four hours of deliberation.

The March 24, 2010, incident began about 10 a.m. A male had called 911 and said, after a long pause, “Yeah, I need help. Because you’re a bunch of liars.” The line went dead.

Reilly responded to the call at the house in the 1600 block of Birmingham Street. While waiting for another officer to arrive, she decided to go in by herself. She testified that Swenson’s mother, Frances Swenson, answered the door and whispered, “He’s been threatening us, and he’s been drinking beer,” referring to her son, who stood in the living room.

During their testimony Friday, Swenson’s parents denied that. They said they answered the door together, and neither said anything about their son threatening them.

They also claimed that Reilly suffered her injuries by tripping on a low table and hitting her head while running to intercept Swenson.

“I thought she was stunned, but she seemed wide awake,” Swenson’s father, Maurice Swenson, testified. “She got up and took off like she never even been touched.”

Both parents said their son never spoke to Reilly, scowled at her or laid a hand on her. They agreed with Reilly that their son resisted her attempts to handcuff him, but claimed he hadn’t done anything, and fled after Reilly hit him with a Taser and sprayed him with chemical irritant.

The parents testified that they had been talking that morning with their son about a $100 bill he dropped on the floor. Maurice Swenson found it, and refused to give it to his son right away, he said. The parents were afraid he would spend it on liquor, they said.

Thomas Swenson has a drinking problem; he also is bipolar, they said.

Prosecutor C. Ryan Tennison argued Friday that Swenson’s parents told a different story to police on the day of the incident. They never said anything about Reilly tripping. They have talked since, getting their stories together, he said.

At least 18 St. Paul police officers, most of them in uniform, gathered in the courtroom for closing arguments in the case.

Sentencing is set for 1:30 p.m. Sept 16. District Judge Lezlie Ott Marek ordered that Swenson be held in custody without bail until then.
