The bodies of David Conde Jr., 2, and David Conde Sr., 59, were discovered in their home in Hamilton Street, Geneva, on February 15.

Investigators said there was no obvious cause of death or visible signs of trauma on either David, according to The Post-Standard.

Ontario County Sheriff’s Office (OCSO) deputies said on Monday that Conde Sr. had died first as a result of cardiovascular disease.

Investigators said his son died of starvation sometime after Conde Sr. perished, the newspaper reported.

In a news release obtained by The Post-Standard, deputies said: “It is believed Mr. Conde passed away first and the child was not able to obtain nourishment after his father passed.”

According to the Centers for Disease Control and Prevention, about 805,000 people in the U.S. have a heart attack every year.

It added: “About 697,000 people in the U.S. died from heart disease in 2020 - that’s one in every five deaths.”

Police first arrived at the home to carry out a welfare check after the father and son had not been seen in about a week.

According to the Democrat And Chronicle, Lt. Joe Murphy said: “There were no signs of a struggle in the residence. We do not have any reason to believe anybody else was in the apartment when these two passed away.”

Lt. Joe Murphy told the newspaper on Tuesday that both bodies were found together in the bedroom of the apartment.

According to Conde Jr.’s obituary on Legacy.com, he is survived by his mother Michelle Travers, his six brothers, and his maternal grandmother.

His obituary read: “David was born in Rochester on October 29, 2019, a beautiful baby boy with curly locks, that had a determined smile and sweet disposition.

“Despite his medical condition at birth, he had recently learned to walk, following many surgeries and months of casts and rehabilitation.”

The investigation into the deaths has now been officially closed, deputies said on Monday.

Newsweek has contacted the OCSO for comment.

In March, a nine-year-old boy was found dead in mysterious circumstances by his sister in Utah.

Logan Gagnier, who lived in Eagle Mountain, went to bed on Friday and never woke up, according to his family.

The family noticed the boy appeared to be late waking up on a Saturday morning and that the discovery was made shortly afterward.
