A wake was held Monday for a mother and her three children who were murdered in their West Brookfield home, a horrific crime that shocked residents of the small Worcester County town of 3,700 people.

The deaths of Sara M. Bermudez and her children — Madison M., 8, James C., 6, and Michael E., 2 — remain under investigation by Worcester District Attorney Joseph D. Early Jr.’s office, which has asked for the public’s help in locating a yellow gas can that was discovered missing from the Bermudez home.

The victims suffered burn injuries, the Globe has reported.

The bodies of the victims were discovered March 1 after Moses C. Bermudez called from California, where he was working, and told relatives he could not reach his wife and children.

His father went to the couple’s home at 10 Old Warren Road and found the bodies, the Globe has reported.

No arrests have been made.

Sara Bermudez, who was 38 years old, was a native of El Salvador, where she and Moses started their family before they moved to California several years ago. The family then moved to West Brookfield, according to an obituary.

“They moved to Massachusetts to enjoy the beauty of the country and to be surrounded by their loving family,’’ the obituary states.

“Sara was a homemaker with a love for God and family. Madison enjoyed being the true princess, with a smile always on her face,’’ the posting reads.

“James was always running around playing and laughing at his own inside jokes. Michael was the joy and reflection of his siblings. The family enjoyed many outings to Chuck E Cheese.’’

The wake was held at Varnum Funeral Home in West Brookfield.

A funeral Mass was scheduled for Tuesday at 10 a.m. in All Saints Church in Ware, according to the obituary posted by the Varnum Funeral Home.
