Enrique Munoz Blanco, 38, was found shot to death late Saturday in a Royal Palm Beach home.

ROYAL PALM BEACH — A violent Saturday night in a Royal Palm Beach neighborhood, which included a home invasion, murder and exchange of gunfire, is tied to one man, say Palm Beach County sheriff’s investigators:

Javier Medina Tamoya.

The 20-year-old is accused of invading a home on the 900 block of Linda Court shortly before 10:30 p.m. Saturday, killing the 38-year-old man inside, threatening his fiancee at gunpoint and shooting at a neighbor as he fled.

The neighbor returned fire, leaving Medina Tamoya with a gunshot wound to his leg and sheriff’s authorities with a “person of interest” in Enrique Munoz Blanco’s shooting death.

Authorities quickly arrested Medina Tamoya on an attempted murder charge for shooting at the neighbor. And on Tuesday morning, investigators announced he also was behind Munoz Blanco’s killing and faced a homicide charge, along with charges of armed burglary, robbery and home invasion.

Records released Tuesday afternoon explain how the exchange of gunfire in which Medina Tamoya was injured were tied to the homicide about 50 feet from where authorities found him bleeding off Camellia Drive east of Royal Palm Beach Boulevard.

It began with a bang. Munoz Blanco’s fiancee told authorities she heard a loud noise from the living room while they were asleep in bed and woke Munoz Blanco.

He walked to their back door and his fiancee heard another bang. She screamed.

“They shot me,” Munoz Blanco reportedly told her. A single gunshot to the chest killed him.

The man in the black hooded sweatshirt wearing a skeleton mask over the bottom half of his face walked in through the broken glass door and pointed a gun at Munoz Blanco’s fiancee. She begged for her life before running from the home.

She noticed an unfamiliar bicycle outside.

Meanwhile, the neighbors heard the bangs and the woman’s screams.

One man brought his gun outside to investigate and saw Medina Tamoya riding away on a bicycle.

He yelled “Hey!” and Medina Tamoya started shooting, neighbors told authorities.

The neighbor fired back, injuring Medina Tamoya.

Authorities found Munoz Blanco’s jewelry with Medina Tamoya, who lives about a mile north of where Saturday night’s violence occurred, when he was being treated at St. Mary’s Medical Center in West Palm Beach.

He indicated that he knew two people who lived near Munoz Blanco but denied being involved in the fatal shooting.

Munoz Blanco’s death marks the 63rd reported homicide this year in Palm Beach County and the first in the village, according to a Palm Beach Post database.
