Maryland authorities have entered day five of their search for Robert F. Kennedy’s great-grandson just 24 hours after his mother's body was pulled from the Chesapeake Bay.

Maeve Kennedy Townsend McKean, 40, was found dead in 25 feet of water just after 5.30pm on Monday by the Charles County Dive and Rescue team, authorities said.

Crews had been searching for Maeve and her eight-year-old son, Gideon, since last week after they went missing Thursday evening when they ventured out on a canoe into the Chesapeake Bay.

'The Maryland Natural Resources Police, along with allied agencies, are actively searching,' a department spokesperson told DailyMail.com Tuesday afternoon.

Police previously said that Gideon is also presumed dead.

Maryland authorities have entered day five of their search for Robert F. Kennedy’s great-grandson, Gideon (pictured with his mother, Maeve), just 24 hours after his mother's body was pulled from the Chesapeake Bay

Maeve, a public health and human rights lawyer, was found about 2.5 miles south of the Shady Side, Maryland home of her mother, former Maryland lieutenant governor Kathleen Kennedy Townsend, who served in the position from 1995 until 2003.

Maeve was one of Senator Robert F. Kennedy's granddaughters and a great-niece of former President John F. Kennedy.

The mother and son disappeared on Thursday as they were canoeing in Chesapeake Bay, Maryland.

They climbed into the canoe to retrieve a lost ball from a waterfront home and they failed to return to shore.

Both McKean and her son were seen struggling to return to shore.

A search conducted by the US Coast Guard ended for the two on Saturday but state Natural Resources police continued it.

Neighbors and members of the DC community left cards to Maeve and her young son on a tree outside their Washington, DC, home following news of their disappearance

The family had moved out of their Washington, DC, home into the Shady Side, Maryland home of Maeve's mother to escape the coronavirus outbreak.

Maeve served as the executive director of the Georgetown University Global Health Initiative.

She graduated from the prestigious Washington, DC, college with a law degree.

Maeve married her husband David McKean in 2009 and together they shared three young children – Gideon, eight; Gabriella, seven; and two-year-old Toby.

Over the weekend McKean shared a heartbreaking Facebook post paying tribute to his wife after she and Gideon were assumed to be drowned.

In his Facebook post, David explained that he and Maeve had decided to take their children to a family lakehouse in Shady Side, Maryland to give them more space to play during the coronavirus lockdown.

'Maeve and Gideon were playing kickball by the small, shallow cove behind the house, and one of them kicked the ball into the water. The cove is protected, with much calmer wind and water than in the greater Chesapeake. They got into a canoe, intending simply to retrieve the ball, and somehow got pushed by wind or tide into the open bay,' David stated in his post.

McKean's mother is former Maryland Lt Gov Kathleen Kennedy Townsend, who is the eldest daughter of the late Robert F. Kennedy and niece of the late President John F. Kennedy. Kathleen and Maeve are pictured above in 1995

About half an hour later, the mother and son were spotted far from the shore by a neighbor, and the police were promptly called.

'After that last sighting, they were not seen again. The Coast Guard recovered their canoe, which was capsized and miles away, at approximately 6:30 yesterday evening,' David somberly stated.

Authorities said at the time their boat appeared to have been 'overtaken by the strong winds' that day.

David remembered Maeve as his 'best friend' and 'soulmate'.

'You could hear Maeve's laugh a block away—and she laughed a lot. She was magical—with endless energy that she would put toward inventing games for our children, taking on another project at work or in our community, and spending time with our friends,' he stated.

Tributes have poured in for Maeve and her son, many from the extended Kennedy family still reeling from the death of Robert F. Kennedy's other granddaughter Saoirse Kennedy Hill who died of an overdose at the age of 22 last year.

Saoirse, who was the daughter of Courtney Kennedy Hill, is Maeve's cousin.

Kennedy Townsend released her own statement about the presumed death of her daughter on Friday night.

'With profound sadness, I share the news that the search for my beloved daughter Maeve and grandson Gideon has turned from rescue to recovery.'

Meanwhile, Maeve's cousin and Massachusetts Senate hopeful, Joe Kennedy III, also released a statement.

'We love you Maeve. We love you Gideon. Our family has lost two of the brightest lights,' he wrote on Twitter, fearing the worst.

New York Governor Andrew Cuomo was married to Maeve's aunt, Kerry Kennedy.

On Saturday, Governor Cuomo's daughter, Michaela Kennedy Cuomo, also shared her personal tribute.

'Maeve (my cousin) and Gideon (her son) had smiles that burst through their eyes and bought joy to all those around them,' 22-year-old Michaela wrote.

'Not being able to hold loved ones close and be together is crushing.'
