Vanessa MacCormack, a second-grade teacher and mother of a 1-year-old girl, was found dead in the couple's Massachusetts home Saturday

The husband of a second-grade teacher and mother who was found dead in her Massachusetts home Sunday was arrested on Tuesday and charged with her murder, PEOPLE confirms.

Andrew MacCormack, 29, was arrested at Revere police headquarters in the death of his wife, Vanessa MacCormack, 30, authorities announced in a statement.

The state’s Office of the Chief Medical Examiner made preliminary findings that the young mother had suffered a blunt force injury to the head, sharp force injuries to the neck, and asphyxiation, the statement says.

“Evidence suggested that the killer made concerted efforts to clean up the crime scene and dispose of related items,” the statement says.

Andrew MacCormack is expected to be arraigned tomorrow in Chelsea District Court. He has not entered a plea and it is unclear whether he has retained an attorney.

“The evidence suggests that her murder was a crime of domestic violence, committed in the very place where she should have been safest — her own home,” Suffolk County District Attorney Daniel F. Conley said in the statement. “It was critical during the past several days to withhold certain information as we gathered the facts and evidence, and we’re extremely grateful for the cooperation of witnesses and partner agencies who helped us build this case.”

Revere police and emergency medical personnel responded to the couple’s ranch-style home just after 3:30 Saturday afternoon following a 911 call placed by Andrew MacCormack, say authorities.

They found Vanessa MacCormack, inside, with obvious signs of physical trauma. She was pronounced dead at the scene.

On Sunday, Andrew MacCormack was spotted at the residence retrieving a baby chair before breaking down and crying, local news station WBZ reports.

Victim Was ‘True Definition of a Family-Oriented Person,’ Says Sister

The couple had been married for over two years, according to their Facebook pages. Andrew MacCormack is a drywaller who studied criminal justice at University of Massachusetts at Boston, his page says.

By outward appearances, the couple seemed to be in love. In November 2015, Vanessa MacCormack posted pictures of her husband carrying her over the threshold of the home they had apparently recently purchased, saying, “Moving on to the next chapter in our lives! I love this man more than anything and I am so happy we are finally homeowners.”

Earlier this week, Vanessa MacCormack’s sister Angela Masucci remembered her as a devoted mother.

“Words could never describe my sister,” she said, CBS News reports. “My sister was the world’s best mother, she did everything for her daughter and had so many plans for her. She never missed an opportunity to bring her places to show off her beautiful baby.”

Masucci added, “She is the true definition of a family-oriented person,” the outlet reports. “She always held get-togethers at her beautiful home that she designed to be like a home on HGTV, and always strived to get the family together.”

MacCormack was beloved as a teacher, Dr. Mary Dill, Principal of William P. Connery Elementary School, said in a statement.

“Our school community is heartbroken,” she said in the statement. “Vanessa was loved by students, parents, and colleagues. She was involved in every aspect of the school and a great friend to everyone on the staff. She will be dearly missed. Our thoughts and prayers go out to her family.”
