Schumer says he's been in touch with the District Attorney's office.
46-year-old Abdulsalam Al-Zahrani of Saudi Arabia is charged with 2nd degree murder.
He's accused of stabbing and killing Binghamton University professor Richard Antoun last Friday.
The Saudi consulate retained a lawyer for Al-Zahrani.
This is Broome's second criminal case with international involvement in two years.
Miladin Kovacevic was one of 3 men charged with beating Binghamton University student Bryan Steinhaur in 2008.
A Serb consulate worker helped Kovacevic leave the US after posting bail.
"We have to make sure it's not like the situation with Bryan where this person flees the county. The law enforcement authority says they're keeping a careful eye there," says U.S. Senator Charles Schumer.
Kovacevic was a basketball player at BU.
He is being tried for assault in Serbia.
