A Florida father and son were arrested on Tuesday after deputies caught wind of a murder-for-hire plot in which the older man's mother was the target. The two schemed with a homeless man to kill the woman for monetary gain, police say.

Suraj Narine, 44, and his son Christopher Narine, 20, had been searching for someone in the homeless community to kill Suraj’s mother,

Magdalene Narine, 73, TCPalm reports. Michiel "Shorty" Hamons, who had a criminal history, was approached by the men to carry out the killing in exchange for $10,000.

Deputies said the Narines wanted Hamons to inject Suraj’s mother with insulin, put her in a car and push it into a canal, according to TCPalm. The plot was thwarted when deputies were alerted by a fourth man who had knowledge of the plan.

Deputies said Christopher Narine told them he was "scared of (his father) and felt pressured" to participate in the murder-for-hire plot.

Both Narines were unemployed, and deputies said the plot was "financially driven," TCPalm reports.

Suraj and Christopher Narine were arrested and charged with solicitation to commit first-degree murder and conspiracy to commit first-degree murder. Hamons was arrested and charged with felony conspiracy to commit first-degree murder.
