The newspaper reports that police in Elgin County are looking at Grant, 52, as a person of interest in the October 2011 death of Daniele Lee Wood, 36. And relatives said that Adriana Laster, 28, was last seen in September 2011 with Grant in South Carolina, reports CBS Miami.

Laster's 11-year-old daughter still lives in Homestead with her grandmother. The girl said she and mother would keep in contact through phone calls almost every other day, but those calls have stopped.

Laster was last seen with Grant in South Carolina. Now, a year later, Grant has been named a person of interest in her disappearance.

According to CBS affiliate WLTX, a report from March 2011 says officers found Laster crying as she lay on the ground. It said Grant "grabbed her by the hair and slammed her face into the side of his mother's house and drug her to the car."

The report says they fought on the way home from with Grant "pouring some sort of fuel on her" in the car.

WLTX reports the report went on the say Grant slammed Laster's head into a brick wall. Police found and photographed various cuts, bruises and other injuries on her body.

According to the report Laster refused medical treatment at first, but later told police she was three months pregnant and consented.

Police were unable to find Grant that night and another criminal domestic violence report was filed the following day with Laster telling police Grant assaulted her again for reporting him to law enforcement. Police found her that day bleeding from the head.

Grant later turned himself in and could have faced a tougher charge, but the Elgin Police Department says Laster had to be subpoenaed to testify against him, according to WLTX.

Laster was later reported missing by her family in September 2011.

"He's a monster," said Richland County, S.C. Sheriff Leon Lott said at a press conference last week regarding the disappearance of 15-year-old Gabbiee Swainson. Grant is charged with kidnapping in that case.

Sheriff Lott said Grant is not cooperating with authorities as volunteers and detectives continue searching for Swainson.

"We believe that she's alive," Sheriff Lott said. "Where and how, I don't know."

Laster's loved ones aren't quite as optimistic in her case. They say the young mother had been in trouble before, mostly for drug related offenses, but they're hoping the community will put her past mistakes aside and help detectives close this case.

It's believed that Grant and Laster spent time in Homestead before relocating to South Carolina.

Anyone with information about Laster or Grant is urged to call Crime Stoppers in South Carolina at 1888-CRIME-SC.
