MIAMI BEACH, Fla. – Weeks after a horrific murder in Maryland where police say the killer shot off more than four dozen rounds, authorities have arrested the suspect in Miami Beach.

Investigators say an enraged ex drove over 1,000 miles to commit the crime. Police found evidence inside a Miami Beach apartment on Saturday, leading to an arrest.

Investigators say Crimea Baker and Sean Lange were shot multiple times by Baker’s ex-husband, 33-year-old David Turner on Aug. 27.

Police believe Turner broke into their New Market, Maryland, home and shot off at least 42 shots.

“We believe Turner entered the back door of the residence sometime after 1 a.m., before 1:25, and murdered her and Mr. Lange in the bed in the bedroom firing more than 42 rounds,” Frederick County, Maryland Sheriff Chuck Jenkins said.

Inside at the time were Baker’s children, who were not hurt during the shooting but hid for hours before calling police.

“I’ve never seen anything to this degree, really it was unbelievable,” Jenkins added.

Jenkins said Turner drove from Miami Beach to Maryland to kill the couple.

It would be weeks before the FBI and Miami Beach and Fort Lauderdale police would cuff Turner following search warrants on his car and Miami Beach apartment and an alibi that didn’t match up.

Video shows a SWAT team going into the Miami Beach building off West Avenue. That is where police say they found evidence to get that arrest warrant. Investigators believe this may have been a crime of passion that was domestic-related.

“There is no explanation that I can think of that would have justified anything like this,” Jenkins said.

Turner will be extradited to Maryland soon to face two counts of first-degree murder and home invasion charges. He was being held in the Broward County jail.

Baker’s family has set up a GoFundMe page for those children who are now left without their mother.
