Chilling security camera photos capture final moments of teacher Marisa Galloway’s life before being killed by former mother-in-law

Chilling security camera photos captured the final moments of special ed teacher Marisa Galloway’s life before she was killed by her former mother-in-law — who was seen trying to hide her handgun behind a Target tote bag just minutes before the shocking murder-suicide.

Galloway, 45, can be seen packing her child’s stroller into the back of her car on a tree-lined street a block from Gracie Mansion on the Upper East Side just before 9 a.m. Friday, the images showed.

Her former mother-in-law, Kathleen Leigh, was also spotted standing to the side with her right hand bizarrely covered by a Target shopping bag.

A few moments later, Leigh, 65, fatally shot Galloway before turning the gun on herself.

Galloway’s 1-year-old daughter, who was in the backseat of the car, was unharmed.

Leigh, a retired Chicago probation officer, left a rambling, seven-page suicide note in which she accused Galloway of trying to isolate her 4-year-old daughter from Leigh’s son, the girl’s father.

The letter, which was addressed “For Police,” also claimed that Galloway abused the girl — an accusation that was already found to be untrue by city child services investigators.

Galloway and Leigh’s son had been engaged in a bitter, drawn-out custody battle that included allegations of abuse from both sides.

Neighbors in Leigh’s East 79th Street building added that she frequently complained about Galloway supposedly mistreating her granddaughter.

Between July and November 2021, police recorded five domestic incidents involving Galloway and her ex.

The father complained in several reports that his daughter came home with bruises, sources told The Post.

Galloway’s in-laws’ accusations, however, did not match up with how others in her life described the mom of two.

“She was so wonderful and she loved her kids,” one resident of Galloway’s East 86th Street building tearfully told The Post last week.

The 4-year-old girl is in her father’s custody as police continue to investigate the murder-suicide, sources said.

She was also with her dad when her grandmother turned a gun on her mother and then killed herself, they noted.

As of Monday, police believe that Leigh — who was also receiving treatment for terminal cancer — acted alone, and that her son had no idea of his mother’s plan.
