WEST HAVEN — The fourth suspect in an October homicide was caught and held in custody Wednesday, following a month-long search by authorities who arrested the other three alleged perpetrators in December.

The police department with help from the U.S. Marshal Office arrested Anthony Adams, who was arraigned Wednesday in Milford Superior Court, according to Officer Bret Schneider. Adams faces charges of felony murder, conspiracy to commit first-degree robbery and attempt to commit first-degree robbery, Schneider said. Court records say he has not been released from custody and is held in lieu of a $1.5 million bond.

Anthony Adams, 26, of 90 Rockdale Road, is the brother of another suspect in the case, Daquane Adams, 24, of 60 Plainfield Ave. Eugene Walker, 26, of 22 Lattanzi St., and Alexis Morrison, 19, of 90 Rockdale Road, are also accused of playing a role in the shooting death of Neville Malacai Registe, authorities said.

Authorities found Registe, 22, unconscious in a vehicle on Glade Street near the West Haven Housing Authority pinned against a utility pole early Oct. 29, just before Hurricane Sandy hit the region. It’s believed his gunshot wounds led to his car accident. Registe was transported to the hospital, where he later died, police have said.

Daquane Adams and Walker also face charges of felony murder, conspiracy to commit first-degree robbery and criminal attempt to commit first-degree robbery, and are still being held in lieu of $1.5 million bail each, according to court records. Morrison is charged with second-degree hindering prosecution, conspiracy to sell a controlled substance and conspiracy to sell a controlled substance within 1,500 feet of a school and is being held in lieu of $250,000 bail.

Warrants in the case have previously been sealed while authorities looked for Adams.
