A 41-year-old man accused Feb. 18 of firing at least eight shots toward his father, killing him, did so after an argument about taking the dog out, according to statements in an affidavit released Feb. 19.

Sheldon Morrison was taken into custody in the Hollywood area hours after Port St. Lucie Police said he fatally shot his 69-year-old father, Glen Morrison, in a garage of their home in the 5900 block of Northwest Ketona Circle, which is off West Torino Parkway, east of Interstate 95.

Sheldon Morrison is in the St. Lucie County Jail on a first-degree murder charge.

Investigators were called about 7:47 a.m. Feb. 18 to the scene.

Glen Morrison’s wife, Patricia Morrison, told investigators she heard her husband and son arguing in the garage about taking out the dog.

She went to try and stop the quarreling, and when she got in the garage saw her husband and son.

“She described Glen as being very agitated and angered,” the affidavit states. “She described Sheldon as being calm.”

She said her husband was “banging water containers around.”

He “aggressively” walked up and was close to her, but did not touch her, she said. Patricia Morrison did not think her husband would have done so.

Sheldon Morrison went into the house and then came back to the garage.

“While looking toward her husband and Sheldon out of her view, she heard a bang,” the affidavit states. “She turned toward Sheldon and saw him holding a firearm pointed at the direction of Glen.”

She followed Sheldon Morrison back into the house and “made comments toward Sheldon on why he did that.”

She said Sheldon Morrison responded, “I thought he was going to hit you.”

She said she watched as Sheldon Morrison left in his beige Cadillac.

Police found eight cartridge casings on the ground next to Glen Morrison.

Police reported Sheldon Morrison has no criminal history, the affidavit states.

Investigators learned there is no history of physical violence between Glen Morrison and Patricia Morrison, and there also hasn’t been physical violence between Glen Morrison and Sheldon Morrison.

“She did not hear any statements from either subject about physical violence not did she see any physical interaction between the two subjects,” an affidavit states.

Patricia Morrison also said she didn’t see anything in her husband’s hands that could be considered a weapon.

She told investigators her son isn’t diagnosed with a mental health issue, and she didn’t think he was under the influence of anything.

Neighbors

Neighbor Donna Tighe, 56, spoke to TCPalm Feb. 18 before police identified the deceased or his son.

She said her husband would go out and speak to a man who lived at the home and worked on cars, and said things were very social.

“That’s why this is, like, crazy,” Tighe said.

She said she didn’t hear anything.

“They banged on my door at 8 o’clock this morning asking us if we heard a pop,” Tighe said. “I said I didn’t hear anything, I was sleeping.”

Tighe said she didn’t expect anything like this to happen in the area.

“Not in this neighborhood. It’s so quiet,” Tighe said. “This is uncalled for, totally.”

Mitchell Oxendine, 78, lives on the opposite side of the street from where the incident occurred. He said he knew Glen Morrison.

“Nice guy, quiet. Most people in this neighborhood, they kind of stay to themselves,” Oxendine said. “He comes out, I see him, I talk to him, he walks his dog.”

Oxendine said he’d seen Sheldon Morrison and spoke with him a few times.

“He seemed to be all right,” Oxendine said. “If they were arguing or whatever, it was an inside argument.”

Oxendine said his dog, a Doberman Pinscher named Brandi, came to the door and was barking.

“I came and looked at the door and I didn’t see anything, but she kept growling, looking across the street,” Oxendine said. “And I went back and sat down and ate and then the police came.”

Neighbor Christopher Kasloski, 45, said he had few interactions with Sheldon Morrison, but he interacted with his parents a good bit.

“We sold them that lot when they built their house, so my mom would speak with them all the time when they were building the house about how the progress was going,” he said.

Kasloski said the elder Morrison would ask about how he’s doing and about his mother. He said they’d lived there several years.

“I’ve never seen anything from them or from that house that would even hint at something like this,” Kasloski said.
