Deputies: Brother-in-law accused of killing Eustis woman, held on federal immigration warrant
TAVARES, Fla.—An arrest warrant has been obtained for the brother-in-law of a Eustis woman found murdered in May.
Monica Islam, 44, was found shot to death near Scenic Hills Drive and Wolf Branch Road outside of Mount Dora around 7:30 a.m. May 2 after vanishing from Shell, 1701 South Bay Street, Eustis around 6 a.m. the same morning.
According to the missing person report obtained by Inside Lake, Islam’s daughter, Rimi Islam, reported her mother missing around 8:30 a.m. May 2. She told Eustis Police Department they left their home around 5:30 a.m. and arrived at Shell shortly after. She said her mom helped her with opening the store and then she went outside to take a walk around the parking lot, which was normal behavior.
Rimi Islam told police she got busy and lost track of where her mom was. Another employee told Rimi Islam she saw Monica Islam in the parking lot as she arrived at work, around 6:10 a.m. Rimi Islam tried calling her mom, who had left her purse behind at the store, and was unable to reach her. After going back to the home they shared and looking for Monica Islam and checking security cameras for her with no success, Rimi Islam reported her missing to EPD. While investigating Monica’s disappearance, EPD was made aware of a body found near Mount Dora; later identified as Monica Islam.

Islam was found in Lake County Sheriff’s Office jurisdiction; deputies responded to the scene and detectives took over the investigation. Through its investigation, LCSO found that Monica Islam had been the victim of a domestic violence committed by her husband, Rashedul Islam, and his brother Shahidul Islam in December 2024, in Eustis, LCSO Capt. John Herrell said in a press release.
In that incident, Rashedul Islam reportedly struck his wife and stole jewelry and paperwork related to a property in Bangladesh. Shahidul Islam pointed a gun at his sister-in-law and told her not to call 911, Herrell said. It was reported to EPD and Rashedul Islam fled the country before he was arrested.
Detectives also uncovered Shahidul Islam had previously been deported and had an immigration warrant for illegally reentering the United states, Herrell said.
Using information from license plate readers (LPR,) detectives connected Shahidul Islam to a home in Sanford and later found out he fled to New York in a rental car. U.S. Marshals located him, he was taken into custody on the federal immigration warrant and has remained in federal custody since May 6, according to Herrell.
“He will be served the homicide warrant and extradited back to Lake County once all the federal requirements related to his immigration status have been satisfied,” Herrell said.
