Unfortunately, not.
This is from the Wikipedia page on John Guica:
"Aftermath of Conviction Reversal
Russo's Confession
On March 22, 2018, Antonio Russo confessed to killing Mark Fisher
[48]. Russo detailed the killing to detectives, in a DD5 that was passed along to Giuca's attorney Mark Bederow. Russo told detectives that he killed Fisher after he and Fisher left Giuca’s home
[49]. Russo goes on to state in the DD5 that the “gun was his”
[50].
Subsequent Bail Hearings 2018
On February 20th
[51] , June 28th
[52], and September 6th, 2018 Giuca was consistently denied bail despite having his conviction overturned.
[53]
Giuca remains incarcerated at Riker's Island until his hearing in February, 2019."
That should be a major habeas suit right there....
