The Weather Underground was a prominent anti-war, anti-U.S. government coalition that carried out a series of high-profile bombings. Founded in the late 1960s on a Michigan college campus, the militant activist group over the next two decades split into factions.
A woman-run faction based on East Coast was dubbed M19CO. They gained fame after breaking out political activist Assata Shakur from a New York prison.
In 1984, one planned M19CO attack happened right across the river from Philadelphia in Southern New Jersey — but the perpetrators were caught. One of the people arrested was group leader Susan Rosenberg, who ended up going to prison on a plea deal, and was eventually pardoned by President Clinton.

This week’s local history threads takes us to a storage facility in Cherry Hill…stuffed with 700+ pounds of explosives and years of intrigue.

Our “Headline of Yore” is from today’s Camden Courier-Post in 1984:
“Group’s leader held on $1 million bail.”

You might know a little about the Weather Underground, a leftist militant group that formed in the late 1960s and carried out a series of high-profile bombings during the latter years of the Vietnam War. pic.twitter.com/gVZ8vqG2Zx

Those attacks included a bombing at the Pentagon on May 19, 1972, the birthday of North Vietnamese leader Ho Chi Minh.

By the mid-to-late 1970s — with America’s involvement in the Vietnam War ending — the Weather Underground began to split into factions.
— Avi Wolfman-Arent (@Avi_WA) December 1, 2022
One of those factions was dubbed the May 19th Communist Organization (M19CO).
M19CO grabbed national attention in 1979, when three of its members freed the political activist Assata Shakur from a New York prison.

Shakur had been convicted of murder in the death of NJ trooper Werner Foerster.
Shakur eventually fled to Cuba…where she remains today. pic.twitter.com/BCWlFQw4dZ
After freeing Shakur, the M19CO remained active for years.

In 1981, members of M19CO robbed a Brinks truck, stole $1.6 million dollars, and ended up killing two Long Island police officers. pic.twitter.com/W2qtxPJX2U
In 1983 alone, the group was reportedly responsible for bombings at a federal building in Staten Island, the National War College, the U.S. Senate, and the Washington Navy Yard.

The group continued to carry out bombings in 1984, but law enforcement was closing in.

And that’s what brings us to a storage unit in Cherry Hill, New Jersey in November 1984…near the intersection of I-295 and Berlin Road…

Initially there were conflicting reports…but police ultimately said that a Cherry Hill officer was doing “routine patrol” at the storage facility around 6:30 pm when he came across two people moving explosives from a trailer into one of the units.
— Avi Wolfman-Arent (@Avi_WA) December 1, 2022
Those two people turned out to be M19CO members Timothy Blunk and Susan Lisa Rosenberg.

Rosenberg’s arrest, in particular, was major news. pic.twitter.com/TqJdErtgeo
Distinct among radical groups, M19CO was largely made up of women. Susan Rosenberg was among the group’s earliest members and leaders, according to Smithsonian magazine.https://t.co/R0X9xY1SyL

At the time of her arrest, Rosenberg was wanted in connection with the Brink’s robbery and was eventually charged in connection to several other bombings.

A top NJ police official called Rosenberg’s apprehension “the next best thing” to arresting Shakur, per the Courier-Post. pic.twitter.com/jjmM3aOJHa
Rosenberg was eventually convicted of explosives possession and sentenced to 58 years in prison.

The government ended up dropping the bombing charges against her and Blunk as part of a broader plea deal with members of the group. pic.twitter.com/dEA8dkAfrr
Though it was not the very end for M19CO, Rosenberg’s arrest in Cherry Hill landed squarely in the group’s final chapter.

By the next year, members were either in prison or on the run.
Susan Rosenberg served 16 years of her sentence before Bill Clinton pardoned her on his final day in office.
— Avi Wolfman-Arent (@Avi_WA) December 1, 2022
Blunk had already been paroled.
By that point, whatever vestiges of the Weather Underground once existed had long been extinguished. pic.twitter.com/e4sgr7mGn2
After her release, Rosenberg worked in various non-profits and wrote a memoir (per wiki).

Blunk, according to multiple sources, became a florist and artist in New Jersey.
A twitter account claiming to be Blunk (@busyhominid) appears to tweet primarily about sports.
