Police in Delaware are investigating after a family of five was found dead inside their Prices Corner home in an apparent murder-suicide.

WPVI reports that Matthew Edwards, 42, wife Julie Burton Edwards, 41, and their children, Jacob, 6, Brinley, 4, and Paxton, 3, were found shot to death Monday night on the home’s second floor. Police said Matthew died of a self-inflicted gunshot wound.

A neighbor who claimed to have spoken with Matthew that Sunday said the father was emotional about work and marital issues, leading the neighbor to advise him to “just worry about your kids.” Neighbors confirmed to KYW-TV that Matthew had recently lost his job.

WCAU reported that Julie often advocated for the Williams Syndrome Association in her social media posts. The Cleveland Clinic describes Williams Syndrome as a “genetic condition characterized by unique facial features, delayed development, learning problems, and certain personality traits.” The condition is linked to cardiovascular issues and poor growth during childhood.

Resident Alisha Garvin told the station that she heard a succession of pops early Monday but didn’t think anything of it, noting that the Fourth of July was days earlier and the noises could have been firecrackers.

It wasn’t until police arrived 8 p.m. that night did Garvin learn that those sounds were likely gunshots.

Garvin told KYW-TV that a boy who was dropped off for a sleepover at 7:30 p.m. walked into the home and discovered the bodies.

Neighbors said they were shocked by the apparent murder-suicide. Brian Covenko said he and his wife often had play dates and the Edwards family. Convento also recalled regularly seeing the father playing outside with his three children.

The family’s bodies were taken to Delaware’s Division of Forensic Science to undergo autopsies which will determine an exact cause of death.
