Police in San Marcos are also looking for a man who allegedly entered an occupied apartment and threatened a resident with a gun at the same complex. This incident happened on Tuesday.

The Retreat

May 2

Officers are searching for a suspect in a home invasion and sexual assault that happened at The Retreat apartment complex on May 2. 

During the press conference Friday, police said they received a call from a victim stating that she and her roommate had been taken at gunpoint inside their apartment at about 12:30 p.m. Thursday. The gunman allegedly proceeded to "bind" the girls before he physically and sexually assaulted them for two to three hours. After the assaults, the gunman fled the apartment complex while the victims called 911, according to police.

Police mentioned that this crime closely matches one of the assaults that took place at the Cottages of San Marcos.

"This crime almost identically matches the crime committed about a week ago," police said. 

The suspect at the Retreat apartment is described as a black man who was wearing black clothes and a ski mask at the time of the incident. This suspect was also reportedly armed with a handgun. Police said this suspect's description also closely matches the suspect in one of the Cottage apartment assaults.

As police were finishing the crime scene at the Retreat, they received a call at about 4 p.m. from a caller who said she heard a woman scream "rape" at the Edge apartments. Officers were able to make it to the scene at the Edge apartments within three minutes, police said.

During the press conference Friday, police said the victim in this case had been in a confrontation with her roommate. The victim reportedly told police she had been sexually assaulted by her roommate, later identified as Louis, on April 29.

Police said she had not seen Louis since the assault happened until Tuesday, May 2, when she returned home and found him inside the apartment. Police said the victim then screamed for help.

Police said they were able to identify the victim's roommate as Louis, who has been accused of sexually assaulting her. 

Police said the suspect in all of these cases has the same characteristics as Louis, but cannot confirm that he is responsible for the other assaults.

Police described the suspect in each of these assaults as a black man in his 20s with an athletic build who is about 6 feet to 6 feet and 3 inches tall. The suspect in each of these assaults was also seen wearing all black clothing.

"That's a similar description to what Louis was seen wearing when he fled the scene at the Edge," police added.
