Four men have been charged with murder, robbery, and conspiracy in the deaths of two men fatally shot in their Glassboro home this month during an attempt to steal money and marijuana from them, authorities said Monday.

Devon Conover and Abdelgadi Hassan, both 19 and of Trenton; Altaifjoe Hassan, 23, of Glassboro; and Daniel Hall, 23, of Teaneck, N.J., are in custody awaiting detention hearings, the Gloucester County Prosecutor’s Office said. The Hassans are brothers, Thomas Gilbert, spokesperson and chief of detectives for the Prosecutor’s Office, said Monday.

The four are accused of killing Manuel De La Rosa Jr., 26, and Shantal Farrow, 36, in their Warrick Avenue home. Glassboro police found the two shot to death while conducting a wellness check about 9:15 a.m. Aug. 19.

In a statement the day after, acting Gloucester County Prosecutor Christine A. Hoffman said authorities did not believe the killings were random and asked tipsters to contact investigators.

The defendants were identified as suspects through cellphone records that showed them on Warrick shortly before 2 a.m. Aug. 19, according to the affidavits of probable cause for their arrests. Conover later admitted to authorities that he had gone to the home with the intent to rob the victims of money and marijuana, his affidavit says.

Altaifjoe Hassan, a former Rowan University student, assisted in planning the robbery attempt, court documents say.

Farrow worked for Rowan’s food-service provider, a school spokesperson said. A GoFundMe page created for him said he was known for his “goofiness and welcoming heart.” Another GoFundMe page created for De La Rosa described him as someone who “was so full of life” and “made us feel at home.”

De La Rosa graduated from Rowan in 2017, university spokesperson Joe Cardona said. He said Altaifjoe Hassan was last a student at Rowan in fall 2019.

Surveillance footage showed Abdelgadi Hassan’s vehicle near the victims’ home around the time of the killings. A codefendant identified Hassan and Hall as being the shooters, the affidavits say.

Conover, Abdelgadi Hassan, and Hall are also charged with gun offenses. The four men are represented by the Public Defender’s Office. Deputy Public Defender Jennifer Sellitti declined to comment Monday, but stressed that the men are innocent unless proven otherwise.

The Prosecutor’s Office said the investigation remains active and asked any witnesses to contact authorities.
