Tuesday was a somber day for many in Yonkers who are mourning the loss of a beloved teacher.

Many people attended the wake for Arlene O'Neill.

O'Neill was shot and killed by her husband inside their Yonkers home last week, according to police. He later died by suicide.

O'Neill was a beloved teacher at Anne Hutchinson Elementary School.

She touched many lives in the school district and beyond.

The O'Neill's leave behind three boys. Fundraisers have been happening to help those kids financially after this tragedy. That includes one Wednesday where O'Neill went to high school.

“Everyone you speak to has these glowing things to say about Arlene's impact on her community. It was important that she was a member of the Sacred Heart family so we want to give back in any way we can," says Kyle O'Donnell, the Principal of Sacred Heart High School.

Details on the fundraiser:

"As part of the larger "Go Green for Arlene" initiative, the Sacred Heart High School family will have a "Jeans for Arlene" $5 modified dress down day on Wednesday, October 23rd. Arlene Connolly O'Neill was a Sacred Heart alum who passed away tragically last week. Arlene was voted “Most School Spirit” when she graduated from Sacred Heart in 1995. Let’s come out in support of her family. Any Sacred Heart alumni or community member who would like to contribute to the fundraising may drop off their donation in the main office of Sacred Heart High School."

Arlene's funeral is Wednesday at 11 a.m. at Annunciation Church in Yonkers.

The school where she taught, Anne Hutchinson Elementary, will be closed for the day so students and staff have a chance to attend the services.

The announcement from the school district:

"Dear Members of the Eastchester School Community, Over the weekend, we learned that the wake for Arlene Connolly O’Neill will be held on Tuesday, Oct. 22, from 1 p.m. to 8 p.m. at the Flynn Memorial Home located at 1652 Central Park Avenue, Yonkers, NY 10710. The funeral service is scheduled for Wednesday, Oct. 23, at 11 a.m. at the Annunciation Church located at 470 Westchester Avenue, Yonkers, NY 10707.

As you know, Arlene was a beloved fifth grade teacher with more than 20 years of service to our children and families in Eastchester. As a testament to the strong sense of community at the Anne Hutchinson School, nearly all staff members requested to attend the funeral service. In honor of Arlene’s memory and to accommodate our staff during this challenging time, we have made the decision to close the Anne Hutchinson School on Wednesday, Oct. 23.

While we recognize that this is a difficult decision for many parents and families, our primary concern is the health, safety and welfare of all students, while at the same time supporting the countless teachers and students planning to attend the service with their parents on Wednesday.

All of the other District schools remain fully open on Wednesday, Oct. 23. If closure of the Anne Hutchinson school causes an undue hardship to you and your family, we have reserved a very select number of student spots at the Greenvale School. If you feel that you need this additional support for your family, please call this special hotline number (914-793-6130 ext. 4821) and Dr. William Meyer, Assistant to the Superintendent, K-12 Student and Staff Services, will review the circumstances of your situation and determine if an alternate arrangement is possible."
