Authorities have evidence linking Roy Den Hollander, the men’s rights attorney suspected of shooting a federal judge’s family on Sunday, to the murder of another men’s rights activist in California last week, FBI Newark spokeswoman Doreen Holder confirmed.

“As the FBI continues the investigation into the attack at the home of US District Court Judge Esther Salas (District of New Jersey), we are now engaged with the San Bernardino California Sheriff’s Office and have evidence linking the murder of Marc Angelucci to FBI Newark subject Roy Den Hollander,” she said in an email to CNN.

Authorities are investigating any possible connections between Roy Den Hollander, the men’s rights attorney suspected of shooting a federal judge’s family on Sunday, and the murder of another men’s rights activist in California last week, according to a law enforcement source.

Den Hollander had a list of possible targets that included several judges, two law enforcement sources told CNN. The people on the list have been notified by the FBI, one of the sources said.

CNN previously reported that federal officials contacted New York state Chief Judge Janet DiFiore after officials found her name and photo in a car associated with Den Hollander, state Unified Court System spokesman Lucian Chalfen said.

Den Hollander was found dead on Monday from what two law enforcement sources said is believed to be a self-inflicted gunshot wound. An “anti-feminist” attorney with a long list of personal grievances and sexist and racist views, he is suspected of fatally shooting the son and injuring the husband of US District Court Judge Esther Salas at the family’s New Jersey home.

Back on July 11, Marc Angelucci, the 52-year-old vice president of the National Coalition for Men (NCFM), was found unresponsive and with apparent gunshot wounds just after 4 p.m. in Cedarpines Park, a community in southern California, according to the San Bernardino County Sheriff’s Department.

Angelucci was pronounced dead at the scene. The suspect was described as an unknown male, and the motive is not known, the sheriff’s department said. The NCFM said he was shot and killed in front of his home.

The suspect in Angelucci’s killing on July 11 was believed to be wearing a FedEx uniform, a source told CNN. Den Hollander appears to have worn a FedEx uniform in the New Jersey shooting of the judge’s family, which killed her 20-year-old son and injured her husband, CNN has reported.
