Police released a wanted poster for Wallace Thursday night and say he should be considered armed and dangerous. According to the station, he is wanted for accessory after murder.

Wallace was reportedly last seen driving a silver or gray 2012 Chrysler 300 with Rhode Island registration number 451-375.

Wallace, also known as "Bo" and "Fish," is described as having a very heavy build. According to the wanted poster, there are active felony warrants in Massachusetts for his arrest.

If anyone has any information regarding the whereabouts of Wallace or the vehicle he was last seen driving, they are asked to call the North Attleborough Police Department at (508) 695-1212.

Hernandez, 23, was charged Wednesday with first-degree murder in last week's shooting death of 27-year-old Odin Lloyd. Hernandez, who was released from the New England Patriots following his arrest, is being held without bail.

Lloyd's body was found in an industrial park less than a mile from Hernadez's home in North Attleborough. In court Wednesday, a prosecutor recounted the events of June 17, saying Hernandez and two other men picked up Lloyd in Dorchester before he was shot.

Carlos Ortiz, 27, of Bristol, Conn., has also been arrested in connection with the murder.

Early Friday morning, Boston police were reportedly at the home of Hernandez executing a search warrant. According to CBS Boston, police are now trying to determine whether Hernandez had a role in a July 16, 2012 double-murder in Boston's South End.

Sources reportedly tell the station that investigators now believe Lloyd may have had information about Hernandez's alleged role in that double-murder.

Prosecutors have said the only information they are prepared to release at this time in regards to a motive in the death of Lloyd is that they believe Hernandez was upset with Lloyd over speaking to certain individuals at a nightclub in Boston.
