He was arrested Monday without incident, police said.
After Wednesday's proceeding, O'Shea-Watson's cousin, Bryan Dunn, said the family wants Monell's fate to be decided appropriately by the state's justice system.
Monell, of the Cedarville section of Lawrence Township, is charged with murder, certain persons not to have a weapon, possession of a weapon for an unlawful objective and unlawful possession of a weapon. "She helped everybody out but the courts didn't help her in this matter, and she is not here with us today", said Dunn. Per bail reform, the court decides whether a person will stay in jail or be released instead of holding them on bail waiting for trial.
According to the 911 call to police about O'Shea-Watson's death, her son found her stabbed and ran to a neighbor's house for help. His family members did not show up, but the victim's family did - and were clearly emotional. There was a $1,000 reward for anyone who gave authorities information regarding Monell's whereabouts.
The body of his 36-year-old wife was discovered by troopers shortly after 8am on December 19 at her home on Raymond Drive in Commercial Township. Authorities have yet to comment on a motive for the slaying.
Dunn said even knowing what O'Shea-Watson was going through with Monell, her murder was a shock.
Friends of O'Shea-Watson alleged Monell physically abused O'Shea-Watson for more than a decade.
The search for Monell eventually became a nationwide manhunt.
Jeremiah Monell, 32 was taken into custody around 3:30 p.m. Monday when police tracked him to the woods behind Angelo's Pizza Shop on Route 54 in Folsom, New Jersey. After his arrest, Monell was taken to Inspira Medical Center Vineland for a medical evaluation.
