Arrest made in shooting death of 16-year-old Emilie Sineace of suburban Lake Worth

Suspect was dating victim for several weeks

SUBURBAN LAKE WORTH, Fla. -- An 18-year-old man has been arrested in connection with the shooting death of a suburban Lake Worth teen Friday evening.

Brandon Nicholas Santos was booked Monday evening into the St. Lucie County Jail and is facing charges of first-degree murder with a firearm in the death of Emilie Sineace, according to a probable cause affidavit by the Palm Beach County Sheriff's Office.

Santos was identified as the shooter by the victim moments before she underwent surgery for multiple gunshot wounds at Delray Medical Center, the affidavit said. An autopsy revealed that Emilie had been shot three times. She succumbed to her injuries Saturday morning.

Emilie's sister, Edeline, told detectives that Santos, a recent graduate of Park Vista High School, had been dating her sister for several weeks.

Detectives were able to retrieve Emilie's cellphone text messages and found that in the minutes leading to the 9:30 p.m. shooting, Brandon had sent a message to her saying that he was driving to her home and to "come out."

In a sworn statement, Santos told detectives that he had been planning to kill Emilie for about two weeks because she had told him during a phone conversation that she wished the son he had with another woman were dead. Her statement infuriated him and he began to plot her death, the affidavit stated.

The affidavit did not specify why Santos was arrested in St. Lucie County.
