Actress Marina Squerciati made a name for herself on crime show Chicago PD and despite the fame, she kept her family life a secret.
But the 36-year-old actress has recently claimed that she is the daughter of Wall Street mogul John R. Jakobson, who at just 25 became one of the youngest people to buy a seat on the New York Stock Exchange in 1955.
Although she was sworn to secrecy for years, she is breaking her silence after her alleged late father broke his promise and failed to include her in his will.
Actress Marina Squerciati, 36, who plays Officer Kim Burgess on Chicago PD, claims financier John R. Jakobson was her father

The Manhattan financier died of pneumonia in 2017 at the age of 86 and left part of his $100million fortune for his three children from his two marriages - including actress Maggie Wheeler who famously played the role of Janice on the sitcom Friends.
But Marina, his alleged love child, was absent from his will.
According to the New York Post, Jakobson was a ladies man who had several affairs including one with former Miss America Bess Myerson.
Marina is the allegedly product of his affair with her mother Marie Squerciati, who wrote for TV in the 1970s and 80s and wrote for the Village Voice as well as the New York Times.
Her sister says Marie was the prize of many men's affections.
'My sister is and was a very beautiful and talented woman. Guys were always beating down her door,' her sister Gloria Maloney said to the Post.
The affair allegedly lasted for a year and led to Marina's birth in August 1981.
Jakobson went on to marry his widow Joan Jakobson in 1983 with whom they shared a son named Nicholas.
From his first marriage with college sweetheart Barbara Jakobson he had three children, one of whom has passed away.
For her entire life Marina kept her father's identity a secret as he allegedly paid her mother $1,200 a month for more than 20 years - money used for Marina's nanny and for her rent-controlled apartment on the Upper West Side.
