A large bloody knife, a bloody ammunition clip, and a gun were found at the scene of Brandon Marshall's stabbing in April, according to incident reports by officers from the Broward Sherrif's Office and Southwest Ranches and Weston police departments.

The reports, obtained by the South Florida Times and written by nine deputies who first responded to the Miami Dolphins receiver's Southwest Ranches home, contain information not previously released by authorities and detail unusual behavior by an off-duty BSO sergeant.

Marshall, 27, underwent minor surgery after the April 23 domestic dispute, for which only his wife was arrested. Aggravated battery charges were dropped against Michi Nogomi-Marshall on July 29.

The incident reports state deputies responding to a 911 hangup observed trails of blood leading from the Marshalls' front doorway to the kitchen and toward the couple's bedroom, and that a comforter had been placed over a large pool of blood in the front hallway.

A 13-inch kitchen knife covered with a blood and a small but loaded magazine, also bloody, were found, reports state. Marshall later turned over a .380 semi-automatic handgun that he removed from a drawer in his bedroom.

An officer who examined the couple's wounds reported "several straight, clean cuts across both [Marshall's] wrists." When the officer observed Marshall grimacing in pain and holding his side, Marshall explained that he was sore from working out, the report states.

But he had been stabbed, and according to one police report, Marshall was advised to seek medical help or possibly be admitted for examination under the Florida Mental Health Act, commonly known as the "Baker Act."

Nogami-Marshall also sustained cuts on her hands and foot and a bruise on her cheek and said her legs felt bruised, officers documented.

When asked if Marshall had struck her, wrote a BSO sergeant, Nogami-Marshall did not respond.

Several suitcases were found on the floor of the bedroom filled with clothes, officers reported, and an SUV in the couple's driveway was found with its hatchback open and clothes thrown inside.

Nogami-Marshall told officers that she had acted in self-defense but did not elaborate, according to the reports, and Marshall told police his stab wound was the result of his falling on a broken vase.

Deputies collected bloodstained shorts and underwear from Marshall's closet, and a pair of his bloody shoes found in his wife's closet next to shards of glass.

In an unusual move, the first deputies to the scene were told by off-duty BSO sergeant Kevin Swanson to stand down and wait for him to arrive from his home, they reported.

However, another sergeant arrived first, according to his report, and after waiting eight minutes for Swanson to arrive and based on the nature of the call, decided to disregard Swanson's order and approach the home with officers present.

After observing blood in the hallway, the sergeant on scene called for tactical and K-9 backup, according to the reports. But when Swanson arrived, he instructed the sergeant to cancel the responding units as well as a rescue unit, and dismissed some deputies from the scene, his own report states.

One officer's report notes that Swanson told him Marshall called Swanson at home, but Swanson does not include this detail in his own report.

Later, Swanson drove Marshall to the front of his gated neighborhood to meet a friend who drove him to the hospital, and escorted the pair to BGMC when the friend didn't know the way, Swanson's report states.

A BSO spokesman told the South Florida Times that Swanson did nothing wrong.

“It’s a gated community so the sergeant transported him outside to meet EMS,” director of media relations Jim Leljedal said. “It isn’t something we ordinarily do but, because there was a gate that was closed, it was the most expeditious thing to do.”

Marshall, who has repeatedly stated that his wife did not stab him, announced during a press conference from training camp that he has been diagnosed with borderline personality disorder -- but first expressed a desire to end the "villainization" of his wife.

"She's handled this with grace and dignity," he said, adding, "the longer BPD goes untreated, the worse it gets, as you all have seen in my life publicly. I'm still suffering consequences...I still may lose my wife, and that hurts me."
